I was running about 70:1 Full Synthetic Schaeffer 7000 which is what I run in my other engine and it runs great on it, Maybe I just should have put 2-3 tanks of a richer oil mix through it before putting the 70:1....???? Shrug....!

I will find out tomorrow when I run it again if it is cooked on the lower end I guess!

Yes you are right it very well could be a bad main bearing.
