X-2 ^^^ and pass me a beer
Found a tester locally. Will post results later today
A leakdown tester for an auto is not correct.
IF you do a leak test and there are no leaks, and IF you get your carb set to specs and IF you set your idle correctly, and IF you plug chop to confirm jetting. it WILL NOT overheat unless you putt around on it or let it sit and idle for long periods of time.
