runs better and throttles higher when intake is blocked

[slawrus]

Carb has been cleaned twice with cleaner and compressed air. Air box is hooked up as well. My diaphragm needle is at 1/2 setting. I wasn't able to see my jet sizes so if I order bigger I won't know the original. I live in Texas so elevation isn't really an issue. Might just get a new 26mm carb and replace gaskets and hoses. The way it's going it may be a complete rebuild but I wanna ride the damn thing!!
