carb boosters
thanks colorado. i will talk to my engine builder he did the first carb amd i did the second and they both do the same thing, so i think the reason is the engine. alot of head and intake port work with real low vacum and i just have to idle it high and am probsably opening the blades up front a whole lot.. my new motor is a high tech engine, but may give the carbs a different signal. what do you think. thanks art in NY
