I've been reeding the post about the Norvel engines, and I've found a lot of good info. One thing that I've noticed is the importance of breaking in an engine. I have a Norvel BigMig .061 that never has run that well. I probably only have about 1 hour of total air time on it because I've spent most of my time trying to keep it running. Needless to say, I never did a break in on it.

Is it too late to go through the break in process? By the way, I took the engine apart and gave it a good cleaning. It looks good as new. I'm using three of the copper rings under the glow plug at the time.

I have 3 other larger engines that have given me no trouble. (OS .25, OS .40, Super Tiger .61)

Thanks for your help. -chris

I say it's never to late! I have heard of guys with engine 30 years old that ran real bad till they went back and did a break in the right way. It sure can't hurt to try!!
