"hello there im a little lost.
"hello there im a little lost. i have a 1999 f15ESHY 4 stroke that will not run. i checked compression. i have 75psi on one cylinder and 80psi on the second. i have removed the carburetor and extra cleaned it twice. and the engine is hooked up to a brand new fuel tank with fresh fuel. i can visually see the fuel sprayed into venturi on carburetor. so now i am after the spark. i pulled spark plugs and put fresh set of plugs in. (NGK-DPR6EA-9) to be exact. the engine cranks all day but will not fire. it will not even attempt to fire. i put a spark checker and there is spark but it seems weak. i looked up specs and i believe as long as the spark jumps 9mm gap, its fine. is this correct? well the spark does indeed jump a 9mm gap.
so i have compression, fuel , and spark
any ideas?
thanks"
