Honda lawn mower fuel valve position

Honda Lawn Mower Fuel Shut Off Valve Position

A fuel valve is not fitted to all mowers but is fitted to all Honda mowers. The valve is also known as gas valve, gas tap, fuel flow valve, petrol valve, gas shut off valve, gas shut off tap - you get the idea.

 

So where is the Honda lawn mower valve positioned? The Honda walk behind mower fuel valve is fitted below the gas filler cap, and beside the black square air filter cover.

 

The nice people in Japan put a sticker on the engine cover to show the gas on and off position.

 

How to Use it?

It's a tap, you know what to do. When left unused they can become stiff. 

 

What's it Do?

It allows the operator to block the flow of gas from the gas tank to the carburetor. All Honda mowers are fitted with one. Some are plastic and are fitted in the gas line. Others are built into the carburetor. On some of the older honda mowers, the fuel valve is built into the on/off control lever.

When to Use it?

The valve should be used when the mower isn't in use. Ideally after you've mowed the lawn, the gas should be shut off until the next use. This takes the load off the carburetor float needle, prevents fuel evaporation and gas leaks.

 

It's also good practice to shut the gas off before transporting the mower in a car or trailer. The constant bumping around would otherwise cause gas to flood the engine, this usually results in a no start.

 

Turn the gas off before making repairs, tune-ups, blade sharpening, cleaning or anytime you need to turn your Honda mower over. 

 

Turning Your Honda Over

Before you turn your Honda mower over, you first need to make it safe. To do this turn the gas off and remove the plug wire. This will prevent the mower from starting and you get to keep your fingers.

 

Honda mowers need to be turned over with the carburetor side up, that's the side with the air filter. This prevents gas spilling from the carburetor onto the air filter.

 

When gas spills onto the air filter, it prevents the engine from getting the right amount of air. This usually causes poor running and black smoke. This is a common complaint, fix is simple, just replace the filter, no harm done.
