Default RE: ZENOAH STILL not pulling fuel ????

Install the carb on an engine you know works right and test it for operation. Initial setting on both needles is 1 1/2 turns open. That will be too rich but the engine will run good enough to dial in the idle, after the idle is set then you can adjust the high speed. I have had to polish the carb body on a surface plate to get the valves to seal properly on a few carbs. I use Tygon fuel line so I can verify the pump is drawing fuel.
