My engine has fuel problems. It will run if I pour some gas in the carb it will run a few seconds. This morning I went to the mower place and brought a rebuilt kit for the pump. I finally got it to stay running but now there is another problem. The pump port on bottom witch is the vac line will leak gas so all the fuel is on top of the carb intake. Could this be a float valve stuck or something else. And is that fuel going into my oil?

If your fuel tank is higher than the carb add a fuel shut off switch in line . About $4.00 plastic valve . The pressure of the fuels weight will make the carb over fill with gasoline which goes into the cylinder head . Depending on which valve is open you fill the muffler with gas or the crank oil - gas/oil mix will ruin the engine quickly .

I'm not really sure what ya have going there...but a shut-off valve is a good thing to do anyway.Good idea to change out fuel line while you are doing it too.Here's a pic...might help ya!jc

Nothing wrong with the fuel shut off valve idea. I ride motorcycle and you will find a shut off on all bikes and they always recommend its use. On all the newer bikes it is vacuum operated and you never have to touch it. I do see a lot of mower do have a fuel valves but they are hard to use. I like the looks of the twist valve you have just before the fuel filter.

Hard to use?I don't understand that.I did think it would a pain to remember to use,but it hasn't been.Now if you couldn't reach it without raising the hood or something,that would be a pain.Well,I wasn't trying to get anything going and think it's a pretty easy and cheap fix for a lot troubles.jc:drink:

I guess you don't know my mowers but on both of them you have to reach under the gas tank to turn the fuel off. jc56 had a picture of one that looked very east to operate and on my bikes its right where you can operate siting on the bike. All the bike valves and jc56 valve is a half turn and off, on my mower I have to turn in a valve. Nothing very hard but it could be a lot easier and to me is a pain to do so I don't. Also on all the newer bikes it is all automatic so you don't have to even think about it and I don't know why they can't do the same thing with mowers.

Oh yeah...I get it now.I have a screw valve under the tank on my Yazoo....It is HARD to use.Hope I didn't offend.Later.jc:thumbsup:

My Roper 16T gas tank is below the seat and the engine is higher up so the fuel pump has a hard time pumping fuel to the carb. I have now thought about buying one of those boat primer thing to help prime the system. I will see if that will help.
