On my new Max Power Extreme engine I have just over 3/4 a gallon through her- I did the breakin heat cycle stooopid rich tank idles- head wrapped- high idle- full throttle- with heat gun applied pre and during tanks- then drove it conservative with head wrapped still progressively leaning until where Im at now- a bit more than 3/4 gallon.

Still I cant turn the engine over by finger when its hot! it gets stuck and has quite a lot of pinch. I would have thought it would be further along the loosening up process. This is my first break in from start to finish.

The real issue is the car off the line (only 10% throttle) just about always has a delayed reaction and I think I have pinpointed it to just being not broken in yet and sticking at TDC? Does this sound about right? I set my idle gap well, I am an above average tuner and troubleshooter so I believe my tune is more than close enough for this stage of breakin for it to at least take off smoothly. The clutch is a new Buku so I dont think its the clutch. Factory settings atm. I was also having issues with the engines immediately stalling as soon as I took the ignitor off- the the engine finally warmed up and I leaned it a little bit and it started to run so I dont think its the plug, fuel or exhaust either. I feel its sticking at TDC as the other symptom I had I heard can be caused by being stuck at tdc (engine dying when removing ignitor). Does this happen with new engines? delayed start off the line?
