does it actually stay running for any amount of time or dying as soon as it starts?
my truck dies as soon as it starts, running off of carb cleaner, there is no gas in my tank....
how is your fuel filter? that $5 part can cause all sorts of problems... how are the fuel lines? it is possible they are fouled or plugged in any way? what about the fuel outlet in the tank?
i remember lilbuddy having major carb issues for a long time.. he ended up somehow having a pine needle lodged in one of his jets!
