As a follow-on to Bob's issue with internal friction on his new engine...
I noticed that there is a lot of internal friction in this engine. I do know that it rotates very freely with everything installed except the piston rings, so I know all the friction is being caused by the rings. It will be interesting to see how much and when the friction lessens during break-in.
It also begs the question about proper break-in proceedure and proper break-in oil. The Great Plains manual says use regular automotive oil and that the total break-in could take 25 hours. I did some searching of the forum and didn't return a lot on break-in.
Any other words, comments, or experiences in breaking in a new engine?
