Hey Steve good to hear from you and thanks for the help, I was asking the information on my engine because it did not seem to have the punch down the straight away so I was going to try leaning it out a little more. I know it could be my gearing also or a combination of things but again it just seem like it did not have that punch or top speed as others. Now I know that most are running top end OS engines and that could be the case.

Again thanks for the reply and help.
