You measure at the highest point across the float. Make sure that the needle valve spring is
NOT compressed when taking this measurement. The needle valve needs to be seated without compressing the spring.
Hold carbs at angle to keep needle valve spring from compressing.
This shows the spring compressed--
not good for measuring float height.
Same here- not good
Tilt carbs at angle, i use a towell to prop them. Take measurement now!
See the 4 pilot circuit holes? These need to be clear for low rpm cruising. Also closer to you is the air screw sticking into the bore. this needs to be clean, clean, clean
Take your time! Triple check the float adjustments! Clean those pilot circuits with carb cleaner and compressed air. Take extra care not to get carb cleaner on your vacuum slide rubbers! once they are swelled be prepared to dish out a few huns :blackeye:
