Evo .46 Question
I have an Evo .46 in an Lt-40 right now. The high speed needle valve has no friction and won't stay where I set it. There is a set screw on the needle valve knob, but it did'nt seem to want to hold it still. Anyone else have this problem and how do I tighten it up? When I run the motor and set it right, the needle valve rotates on it's own to the factory stop on the needle valve. (runs a little richer)
