I need help! slant starts but wont run

i had the same problems.
you have to start by filling a gas can and see if it will run if you hook the fuel pump right to that.
if it does, drop and clean the gas tank. if it still doesnt work change out the lines
if it does not check to see that fuel is getting to the carb. if it isnt check the fuel pump
and finally if it is you need to swap or rebuild your carb. if after all that it still happen time the engine.

note 1: with mine after doing all that it ran for a good while then what would happen is it would run well till it warmed up then it would stall out anytime idle dropped, like at a stop light or stop sign. if this happens it is time to time the engine.

also check and make sure the fuel filter isnt clogged, thats the easiest thing to check and fix and only costs about 5 bucks

good luck
