You guys may be right but I was new to gassers. So I followed the instructions for the first 2 hours at 2500rpm. I don't know why that is in the instructions if your just suppose to go fly it. Then I called Bob at dlusa to find out what he thought. He said not to run it at the 4000rpm but the 2500rpm thing was fine but not needed. That was after I had already ground run it for the 2 hours. My motor runs strong maybe not as strong as some but I'm happy with 6950 on a xoar 22x8 after about 1 gallon at 30 to 1 lawn boy. Bob told me that when You go synthetic you should see about 300rpms more. I can't wait to see that.


What kind of differance did you guys see When you went synthetic? Alot or a little?
