Thanks guys I have been in this hobby 25 years now and I never heard of this method for break in ringed or not. I will do as the instructions say and hope I have better luck with this than my OS91 that I have been fooling with for the last 10 months. The problems that have been posted here with that engine I think I have had them ALL at one time or another. As soon as I would fix one problem another would pop up. Having said that I still think OS is a good engine its just the 91 turned out to be a lemon at least for me.
