I'm having a problem with my motor staying running. I have thoroughly cleaned my carburetors and replaced all parts within carburetor. I have also thoroughly cleaned and replaced all parts within the fuel pump as well as replaced the fuel filter. I have fine tuned the adjustment on the needles within the carburetor. The motor was running for 5 or 6 minutes with the muffs on, seemingly with no problems. The motor died and has been difficult to start since, and if it does start it will only stay on for a few seconds. Can anyone help me with suggestions of what might be wrong at this point?
