Post need help
i have a13hp longtail i removed the governor put stiffer springs in new exhaust and new intake on it. took it out ran like shhit bunch of black smoke wouldnt barely run. removed intake wound up being to small and was making engine run to rich and fouled plug. put stock intake back on took it out today with new spark plug ran like a champ for bout 10 15 minutes then just died like i pulled the kill switch no spittering or sputtering just DIED. now i found out the brand new spark plug iis the wrong size. im thnink it has something to do with spark because it had no syptoms of fuel or air issues since it was running wot for 10 minutes or so and then died. my question is what do yal think is wrong. i thought maybe the spark plug was the issue since its not the right one but why did it run amazing for awhile then die ? other thing i tried to restart it and it wil turn over and try to run on its own for a second or two hen just quit im at a loss what do yal think

Check and see if ya got spark. Could have burnt a coil or somethin? If it's trying to run a little, it has some spark, but see if you can get an inline tester and see how it looks.

Not hearing any funny noises at all? Does that motor have anything electric on it? Possibly a bad ground?

I edited my post. I dunno man. Air, fuel, and spark is what you need. Just got to start tracking it down from there.

If you put your finger on it, it shoulda lit your ass up. I would think your arm should still be numb...
