Thanks Tom. Believe it or not, I have read each and every post on this forum. You are right, there are some great contributions but I don't recall seeing anything about the oil to use in the fuel. I did read about the oil to use on the rockers and where the pushrods contact the lifters. I did a search on Horizon and only found the "Evolution 2-Cycle Oil, Synthetic, Quart". Is this the Evolution Oil you use? If not, could you provide a link? Thanks very much for your help.
