Hey man sounds like you are running it too cold. Make it run at about 190 at least. I killed 2 mach 15's in a very short time cause i had it running way to rich. Cause i didnt have a temp gun :/ I am sorry to say but you might need a rebuild.

Hey guys,
yesterday I went thru the same thing. the only way to get it started and keep it running...was to start it at 1/4 throttle.
had to keep workin the throttle then it would drive.and when I got it around top speed it would not run smoothly.
Had to keep the throttle on to keep it running. If I let off. It would die.
It, in the past (two weeks ago) after about 3 tanks it would get hard to start.
This engine has never run over 160F.
according to frost. do I just need to change out the clutch spring?
