Quote:Piston, rings and cylinder bore are untouched and are as they were before, when it was running just fine.
Wait, you had the jug (cylinder) off????? Did you re-hone the bore?
My grandfather use to say, "you take the piston out of the jug, buy new rings and hone the bore. You'll be sorry if you don't". Yes, I have not always heeded his words
. And, he's was right.
Remember Savage Greg's experience last year.....
EDIT: reason is that when you take the jug off, there is no way you can get the rings lined up to the grooves in the bore. It will take way more mileage to break in the engine.
