> " GRIEF with the Evolution engines"< Now don't get me started on them!! I just bought a TH 75 carb to try in my Evo 61 engine. ITs a last chance for the engine before I toss it in the river! It has really good power when it runs like its supposed to but it won't stay consistant. It doesn't help when you can see that both the neeedle valves are moving by themselves every time you throttle up! [>:]
