Honda iGX Engine Overview

Honda iGX EngineThe electronically-controlled Honda iGX has been making its way into a wide range of equipment including Honda’s own EM and EB series generators. At first glance, it’s easy to confuse a Honda iGX motor with their GX Series, found in pretty much every piece of commercial-grade small engine equipment. That’s understandable since the iGX is a GX at its core, but the iGX has some unique features that change how you need to operate and care for these motors.

What Makes an iGX engine different?

The iGX is based on the GX Series engine, the same design that has been a cornerstone of small engine equipment across the industry, used in everything from generators to pressure washers.

The biggest change is the Electronic Control Unit (ECU.) It can read engine conditions and adjust the governor and throttle, keeping the engine at just the right speed to meet current load demands. The result is fast power response and up to a 15% increase in fuel economy. It’s no wonder that these engines first saw use in generators.

These engines also use CDI ignition with variable timing and a rev limiter. By varying ignition with engine speed, these motors can produce more power over a wide RPM range.

Low Profile Models

For equipment where space is at a premium, Honda offers low profile versions of these engines. These are easy to identify by the large plastic panel next to the recoil starter. This is the cover for the air cleaner. The muffler is located at the rear of the engine, while fuel is stored on the equipment itself instead of a tank bolted to the motor.

The Honda Oil Alert System

The Oil Alert system is designed to protect the engine if it doesn’t have enough oil to stay lubricated. It works a little differently on the iGX than it does on other Honda engines: on some motors, the ECM, located directly above the carburetor, has a small LED light. If it flashes twice, the Oil Alert system has been triggered. On other models, the Oil Alert light is clearly visible next to the ignition switch and will either blink continuously or stay on once the system has been triggered. Most models will shut down to protect the motor, but if a shutdown may be dangerous due to the type of attached equipment, the motor may keep running. If you see the light come on, try to shut down the motor as quickly and safely as possible. Add more oil as needed before starting the engine again.

Starting the Engine

To start an engine with electric start, turn the ignition switch to “Start.” On these engines, the choke is engaged automatically. If it doesn’t start after 5 seconds, release the switch and wait 10 seconds before starting again. If it refuses to start, switch the manual start lever, located next to the ECM, to “On.” Turn the ignition to “On,” then use the recoil starter to start the engine. Don’t move the manual start lever until shutting down the motor.

To start an engine without electric start, locate the fuel lever (lower lever) and choke lever (upper lever) on the carburetor. If you have a low profile engine, which places the muffler and air cleaner behind the engine instead of above it, there will only be a choke lever. If you have an iGX270 or 390, the choke is automatic, so the sole lever is for fuel. Set the fuel lever to open and the choke to closed, as applicable. Turn the ignition switch to “On” and use the recoil starter to start the motor.

Fuses

One or more automotive fuses are used to protect the motor’s electrical system. These fuses are in a clearly marked fuse box on the side of the iGX440, while other motors will have an in-line fuse behind the ignition switch panel on electric start models. A burnt fuse will keep the engine from starting.

Low Power at High Altitude

It should be no surprise when engines make less power at higher altitudes due to the thinner air, but in the case of these engines, this loss in power is due to an incorrect fuel mixture. Honda recommends having the carburetor set up for high altitude use if your motor spends most of its time running at altitudes above 5,000 feet (1,500 m.)

Engine Identification

The serial number and engine model on any iGX can be found on the crankcase directly above the oil drain plug.

Honda HRX Overview

HRX2173HYAPE_IMGLGThe HRX is Honda’s line of top performing mowers, offering all the company’s latest technical advancements including a few industry firsts. What makes these mowers stand out?

Cutting Performance

All HRX mowers use Honda’s MicroCut twin blade cutting system. This design pairs two uniquely shaped blades that sit on top of each other, cutting grass twice in the first pass for smaller clippings when collecting or discharging. When mulching, the dual action chops up grass faster, helping the mower deal with thick and wet grass that would clog other mulching mowers.

These mowers use Honda’s 4-in-1 Versamow System, letting you choose between mulching, bag, or discharge clippings plus a special leaf shredder mode. The bag and deck plug can be attached without tools, and the Clip Director allows clippings to be redirected by moving a single lever, making it easy to switch modes. Continue reading

Which Honda Mower is Right for You?

Honda HRRVLA Lawn Mower - Left ViewLooking to buy a Honda walk behind mower? With over a dozen models to choose from spread over three ranges, picking the right one can be confusing. Here’s what you need to know to find the right mower for your needs.

Honda’s Naming Scheme

Honda has four model lines for walk behind mowers: the HRC, HRS, HRR, and HRX. Models within these lines are labeled using three letters that end in “A” like PKA and HZA, based on equipment. Some model names are used for multiple lines. To make this guide less confusing, the model, line, or a combination of the two will be mentioned as it applies to features. Continue reading

Avoid Making These Common Mistakes With Your Lawn

GrassHaving problems getting that high-quality lawn you crave? Before you start spending serious money on new equipment and care, make sure you aren’t making one of these common, easy-to-fix mistakes.

Cutting Too Much Grass

The shorter you cut your grass, the less often you have to mow. However, trimming the blades down to the ground can severely hamper growth, keeping the grass from getting enough light and water to develop the root system. Each grass variety has a height that it grows best at, but in general warm weather grasses like to be around two inches tall, while cold weather grasses are at their best when they’re an inch tall. Trimming a maximum of one-third of the blade length will make mowing easier on the grass. Continue reading

How to Sharpen a Lawnmower Blade

Honda-Lawnmower-Blades-Birmingham-1To get a quality finish and a healthy lawn, your mower needs to be able to make a clean cut across the grass as it mows. This guide will walk you through inspecting and sharpening your mower’s blade to ensure your mower will slice through blades of grass instead of bruising and breaking them.

Removing the Blade

1. Disconnect the spark plug wire to prevent an accidental start.
2. Tip the lawn mower up on its side so that the carburetor is facing up to prevent flooding.
3. Mark the side of the blade facing out with a permanent marker or some spray paint. This way you’ll know which way the blade will need to be installed after sharpening.
4. Unbolt the blades. On some models, including all Twin Blade mowers, there are two bolts that hold the blade onto the engine shaft. Remove these bolts, but do not loosen the smaller center bolt. If the blade wants to spin, wedge a piece of wood between the blade and the deck. Continue reading

11 Most Common Weeds

1024px-Weeds_in_Waterloo,_OntarioWhat is a weed? It’s a plant that you don’t want in your yard. That’s a pretty loose definition, which means weeds can encompass anything ranging from undesirable types of grass and moss to flowers. Here’s what you need to know to identify common weeds and keep them off of your turf.

Dandelion

Appearing in the spring and fall, their bright, round yellow flowers and puff ball-like seed stage are easy to identify. Dandelions grow long taproots: if you dig these up by hand, you’ll need to remove at least two inches of this root to keep the plant from growing back. Post-emergent herbicides work well on these plants, especially mature ones in the fall, as the herbicide will be able to penetrate the entire root. If you’re developing your lawn, these should fade away as the grass gets thicker, blocking seeds from the soil.

Crabgrass

What’s wrong with grass growing with grass? Crabgrass grows in large, round clumps that stand out from the rest of your lawn. Overwatering, underwatering, and mowing the grass too short can let crabgrass take hold in your lawn. Pre-emergent herbicides work best, but only if applied at just the right time: contact your local extension office to find out when a treatment will be most effective.

Creeping Charlie/Ground Ivy

Whatever you call it, the nodules of this plant grow long stems, each topped by a single leaf. It grows well in shaded, moist areas with poor soil quality but can sometimes appear in sunny areas. Post-emergent herbicides can kill it off, but it may take several treatments. To keep it at bay, plant grass in the area before it has a chance to grow back.

White Clover/Dutch Clover

This clover with its round white flowers is a popular addition to flower gardens and arrangements. At one time it was planted with other grasses in lawns, but a shift in fashion to more uniform turf has turned this plant into a weed. It likes to grow in areas with poor soil quality, and particularly in soil with low nitrogen levels; correcting soil nutrients can usually halt its growth. Broadleaf herbicide treatment is effective, but it may take several applications in the spring and fall to eradicate it.

Chickweed

With thin stems covered in tiny leaves, chickweed grows in areas with moist soil, shade and good soil. It usually pops up in areas with poor grass coverage and poor drainage. This plant can be pulled out of the soil easily, which stops it from spreading. If you have a large area covered in this weed, crush the stems and apply nitrogen, which will be absorbed directly into the plants, killing them. If this weed is a regular problem, apply a pre-emergent herbicide in the spring and fall.

Annual Bluegrass

This blue-green grass appears in late summer, growing in clumps that are much thinner than crabgrass, and can even blend in to fescue lawns. It likes to sprout in poorly-drained soil, overwatered areas, and scalped soil, sprouting seeds on its tips when it germinates. A pre-emergent herbicide can prevent germination, but if this grass is already present, bag your clippings to prevent the seeds from spreading.

Broadleaf Plantain

This perennial has wide leaves and long stems covered in seeds. It tends to appear in areas with thin grass coverage and compacted soil, and thrives in droughts and overwatered areas. Hand-pulling plants and post-emergent broadleaf herbicides work best to remove these plants, while aerating can keep them from coming back.

Violet

While prized by flower growers, this turf nuisance appears in shaded areas with thin coverage. Despite the name, the flower’s pedals can be white, purple, or any shade of lavender in between the two extremes. Steady application of a post-emergent broadleaf herbicide can keep this plant at bay.

Henbit

While other weeds on this list thrive in less than ideal conditions, this plant with its tall, square stems covered in small leaves and small purple or pink flowers grows best in the same conditions as desirable grasses. Post-emergent herbicides can get rid of these plants, while a fall application of pre-emergent herbicide can keep new seeds from taking root.

Wild Onion and Garlic

While different plants, they’re both recognized by their long, thin shoots. Garlic plants have hollow stems, while onion stems are solid. Keeping the lawn mowed, even when dormant, can reduce growth. Some selective broadleaf herbicides on the market are designed specifically for these plants; apply these chemicals when the stems are at least two inches tall.

That means we carry all the OEM parts you need to maintain Honda equipment including generators, water pumps, and lawn care equipment as well as Honda engines found in a wide range ofthird-partyy equipment. How do you get the right parts for your Honda? Here’s what you need to know from identifying your model to finding compatible parts on our site.

Finding Identifying Information for Your Honda

To get the right part, you first need to know what you’re ordering the part for. Honda sells complete equipment as well as engines found in a wide range of industrial, agricultural, and lawn care equipment. For this reason, parts are divided into equipment and engine categories, even on Honda-built equipment, with model numbers and serial numbers issued for both categories.

On equipment, the model and serial number are usually printed together on a tag. Here’s where you find this information:

  • Generator – On the base of the frame, on the bottom of the case, or near the handle
  • String trimmer – On the shaft, either next to the support handle or on the bottom directly ahead of the engine
  • Walk behind mowers – On the deck behind the engine. Older mowers separate this information into two tags
  • Riding mowers, tractors and tillers – The model number is on the hood or the frame cover next to the seat. The serial number is on the side or rear of the frame
  • Single stage snowblowers – On the rear of the frame or on the top of the housing
  • Two stage snowblowers – The model number is on the side of the auger housing, while the serial number is on the rear of the frame
  • Pumps – On the side of the motor. Some pumps have a second frame or pump tag located on the pump housing
  • Power carriers – On the rear of the frame, just behind the bucket

On engines, the model number is on a large sticker on the engine. Engine model names always start with the letter “G.” The serial number is stamped on the side of the engine. It will always be 5 letters followed by a 7 digit number. String trimmers have this information printed on a small tag on the back of the engine cover.

Still can’t find the serial and model number? Check out our “Honda Parts By Series” page to see photos and diagrams showing where the labels are located.

Finding Parts

Once you know your model and serial number, finding the parts you want is easy. Start by selecting between one of the options on the left side of our homepage: Honda Engine Parts, Honda Parts by Series, or Honda Equip Accessories. If you hover over “Parts by Series” you’ll see a few popular options, but don’t worry if you don’t see your model listed: just click on the link, and you’ll be able to search our entire catalog.

From there, just select your model type, model number, and component category using the drop-down menus. This will bring you to a page with an exploded parts diagram and parts descriptions so you can identify the parts you need and add them to your cart.

If you need a common maintenance item and know the part number, we also have the Honda Popular Parts section to quickly find what you want.

I Can’t Find My Honda’s Information. Now What?

Our site includes factory parts diagrams and lets you browse models based on their equipment category. By narrowing down the possibilities and comparing the diagrams with your equipment, you should be able to figure out what you own and what part you need.

I Don’t See a Listing for My Walk-Behind Mower

For some reason, Honda adds a “K” between the 8th and 9th digits to their model numbers in their parts information. That means if the tag says you have an HR123-567890 model, it will be listed in the catalog as an HR123-567K890.

Ordering Made Easy

Individuals looking for genuine Honda parts just have to type in their info and our site will show all of the relevant parts. From there it’s easy to click each part, view a diagram, and add only what you need to the cart. HondaLawnParts.com is a one-stop shop for anyone who needs quality OEM parts.

Understanding Water Pump Terminology

wmp20_pe_imglgWhat is a head, and why is it important? What causes cavitation, and why is it bad? If you’re looking into buying or fixing a water pump, some terms that are used can be confusing. This guide will walk you through meanings and specifications so you can make the right choices when buying, operating, and maintaining a pump.

The Parts of a Water Pump

Consumer water pumps nearly always use an impeller to move water. This is a rotating disc with vanes on it that resembles a fan.

The impeller is held inside a housing called a “volute” or “volute case.” It’s designed to direct water toward and away from the impeller. A tight fit ensures pressure can be maintained. Continue reading
