Mower not getting gas


I have a push mower that will run as long as you pour gas in the carburetor. I have cleaned out the tank and the screen on the pickup tube is clean. It just won't draw gas out of the tank. I left it at a shop once and they supposedly fixed it. First time I tried to start it, it was doing the same thing as before. Pour gas in the carb and it runs till it burns it all. I don't need it, but it bugs me tht it won't run.

Mower not getting gas


What if you take the tubing off and blow in it? Some tanks have a filter inside of them.

Also the Primer bulb only needs a small crack in it to pull air to keep it from getting a vacuum. Same as the primer bulb lines.

Re: Mower not getting gas


Try it with the gas cap loose, just enough to prevent it from sloshing gas out when it runs. The cap has to vent in order for it to draw fuel, so clean or replace it if that helps. If not, I would replace the fuel lines, or at least check them, as Greg mentioned. After that, it's most likely the carburetor. Some carburetors cost little enough that it makes as much sense to replace as to rebuild.

the carb is dirty, it needs tobe taken apart and cleaned out, probaly dirt caught in the needle and seat valve..

Very true, and another convenience invention that causes problems.

If the float isn't floating or the needle / seat function is defective the engine will be flooded with gas rather than deprived of gas.

maybe you missed the part that the mower runs if gas is poured down the carburetor????

And I suspect you missed the part by Greg that stated a vacuum is needed to draw gas from the jet in the carburetor to the combustion chamber not air entering through a cracked line or primer bulb. Hell, I can run an engine without a carburetor by pouring gas in the intake manifold.

again your comment on the carb being flooded is false if it runs by pouring more fuel down the carb..

One thing is for certain, I'll not be bringing a mower to you. I'll take it to someone that can read with comprehension.

Re: Mower not getting gas


Um , Dexter made a good point . If the gas cap is sealing tight , it can create a vacuum .
