I got a new Carb, the speed carb from zoom bicycles.
My engine was running fine but now it only runs with the choke down. It idles Way too high, and bogs down when i throttle. It dies completely with the choke off. So too much air not enough fuel makes sense right?
The fuel slide sits half way down in the venturi when im idling wih closed throttle.
Is my throttle cable too short? Shouldnt the slide almost close the air intake?
I moved the little pac man clip up and down. Nothing changed. The speed carbs needle was a little bent so i thought that might be restricting fuel and switched back to the old needle, but its about 3mm longer.
Is the needle the likely issue keeping the venturi intake open so wide?
Notice the slide in this diagram is 75% closed, mine sits at halfway at idle.
