The sled runs good cold for a minute or so and then power gets real bad and the sled sputters and backfires.
i've tried a different ECM with the same effect.
I took the motor apart and the top end was pretty bad so i bored it and put .020 over pistons. It still does the exact same thing !?!
I can swap it over to carb quick and try that but is this a symptom of center crank seal leaks?
