i was thinking the ip too, but the chain never came off the ip gear, there was always tension between the ip and crack. only the leftside dropped to the pan, but didnt drop off the crack, got cought up. so i dont think i skipped any teeth. i hope...... is there any way to see if the ip is out of sync without removing it?

was the way i set the cam to the crank correct? just by lining up those two mark on crank an cam?
