That's what I did on the MS460 I just rebuilt. I also use 2 cycle oil as my assembly lube. I've run about 2-3 tanks of fuel through it and I'll probably notice a difference in sound/ feel once the rings seat. Usually after 8-10 tanks of fuel and then a good, hard workout. Then I'll check it again and readjust from there.
