Question Even with choke on not enough gas to run underload. Must push primer to keep running. How to adjust carburetor underload condition? Thank you.
Answer fist make sure your fuel filter is not blocked. next on carb . in most cases is 2 settings. 1 being a air mixture needle. and other being fuel. turn them both in lightly til they stop... clockwise. back them out both 1 and 1 half turns. the one on fuel bowl is the fuel. after it is running tweak them as needed. but the fuel should be no less the 1 and 1 half out. give this a try , and lets go from here.
