I was at a buddys place that he just bought and he had an old barn. So I went to check it out and see what relics I could find in there. And I found a strike master power head. I went out and got flighting for it and took all the old gas out of it. It ran and everything, but for some reason it doesn't spin to fast. It also seems like it doesn't have to much power for a 49cc techumcie engine. Would there be anything wrong with it? Or could I possibly do something to make it proform better?
