Before you ask, I have over 5 gallons on the first champion I broke in using this method, havenŽt changed anything on it yet, not a single issue with the con rod, bearings are in great shape and crank pin shows normal wear.
If anyone is having a hard time breaking in these engines just go a little hotter than usual with preheating and problem solved.
yeah the extra heating does make that extra for a easy start and run in.. im swinging between investing in the ty l.ed os or just grab 2 go engines with a 2072 pipe.. would be fun to have choices of the two.. how was the cera udp engine ?? from bottom to top..? and what differences are there between the engine 2years ago and now.. ??
