cant get full throttle
Hey, this could be a number of things. A few I could suggest is to make sure when you apply full throttle that your carb is fully opened. Another likely problem is that the high end is too rich and it can't reach it's full potential. It will have alot of blue smoke coming out the exhaust if that is the problem. But it could be too lean, the engine will stutter and start to sound like it is going to shut off. There could be other issues, so if you can give any more details that would help. I really hope you get it tuned.
