I have a trailboss 325 and in neutral and reverse it revs up like it should, but once I put it in drive it only goes like 20 mph. I put a new primary clutch on it and I put new buttons in the secondary. Don’t know the problem.
The valves were bad with the old top end in it. I have never checked the fuel, but it does run lean because the spark plug has a white tip. I tried adjusting the needle but it won’t do anything. Should I order a new fuel pump?
