    My Briggs&Stratton 18.5 hp V-Twin will not stay running
    I have a Craftsman Lawn Tractor with a Briggs$Stratton 18.5 hp V-Twin engine.The engine model # is 407777 and the type # is 0121-E3. It sat unattended to for two years under my deck that is covered by a roof.So It didn't sit outside in direct weather, it did have
    Some cover.This year I went to try and start it up and the 1st thing I did was to replace the battery, I made sure I had good spark which It has.Turning the engine over I noticed
    It wasn't getting gas even using the choke.So at that point I thought I'd check the fuel pump and I wasn't convinced that it was working properly,So I replaced the fuel pump.
    Turning over the motor again I poured gas into the carb. And It would run as long as the fuel I put into the carb.would allow But would not continue to run from the gas in the fuel tank. So then I thought I'd fill a plastic cup filled with gas with Ahole in the bottom were I took the fuel line right from the carburetor to the bottom of the cup ,So the carburetor was gravity fed,and still the motor wouldn't run any longer than the fule I put into it would allow.I think I've maybe narrowed the problem down to something with the carburetor. Could anyone help me with this beast? Thank You jimyriff
