Brute push mower

I have a Brute push mower that wont stay running... It will run as long as i lift the front wheels off the ground but once i lower the wheels back to the ground to begin mowing it stalls. I have no idea how to fix this issue or whats causing it to happen. Please help me out

 

Are those the drive wheels? If so the problem is likely a poor fuel flow to the carburetor. Tthe extra load of the pull is more than the power level of the engine can handle.

 

How would i possibly fix that? & yes they are the drive wheels

 

Water in the carb can do this. Water is heavier than gas, so if there is just enough in the bowl to kill the engine, when you tilt it, it goes to the corner and allows gas to contact the jet again.

 

To fix that problem if there is water in the gas, take the carburetor off and then clean it with a good carb and choke cleaner you could buy from Home Depot or Lowes in the outdoor power equipment isles. Before taking the carburetor off, I would suggest draining the fuel tank so that when you disconnect the fuel line, there isn't a rush of fuel pouring out onto the mower deck and getting all over the place. You can use an old turkey baster to take the fuel out and into a clear container. If you put it in a clear container, you can let it sit for a little while on your workbench and come back after a while and you should see pockets of water floating on the surface.

Take the carburetor apart and clean everything thoroughly. If it is a Tecumseh engine, there might be a float made of cork. The float has the needle attached to it and floats up and down to control the fuel flow into the bowl. If it is a cork float, disconnect it from the main body of the carburetor and take the little needle that should come out with it as well and shake it by your ear (without the float) and if you hear gasoline in it, that might be causing the problem because the float isn't controlling the fuel properly. Take the main jet out and clean it thoroughly properly as well. It will be in the circular tube on the middle part where the float goes. There is a jet inside there you remove with a flat head screwdriver. If you have a wire brush, pull a single wire out of it and stick it through all the little holes in the sides of this jet. Look through one of the ends to see the middle and make sure that it is going through the holes with not obstructions blocking them.

 

If you find out water is the problem you have to figure out how the water got in the fuel.

If the mower sits outside whether the cover is good or if the container may have been exposed to wet weather.

Ethanol is known to draw moisture, so if you live in a humid area and other fuels such as straight regular gas or premium gas are available I would use those. The extra cost of premium for a lawn mower is negligible.

Another option is an gas additive to absorb moisture. In Iowa we have "Gas Dry" or Heet which are both used for winter gas line freeze where the condensation in the gas freezes in sub zero weather and clogs the fuel lines. I would be surprised if those additives are even on the shelf in the southern states, But there are usually some type of additives like Stabil and Sea Foam around that do the same thing.

 

ilike2mow----------water is heavier than GAS and it will go to the bottom, it will not float to the top. Water that is,,,it will be in the bottom right at the jet port!

 

marbobj, we do have those products down here in the south. They are useful as you mentioned, for small amounts of water int he tank, but they don't do much for water in the carb killing the engine. I'd take the bowl off and dump it at least, and dump and dry the tank if there was water in the carb. If no water in the carb, leave the gas in the tank. If you put it in a container, the water will be at the bottom, not the top.
