RE: 28cc Gas engine not getting fuel? Help please? i have not clue
Can you post a picture so I can see if it's side intake or rear intake. If it's side intake, I believe you have not aligned the carb mounting block correctly. The carb must sense the pulsing of the engine crankcase pressure to activate the pump. There is a small openning in the carb, that must line up with the openning in the mounting block for this to happen. Zenoah offers a carb rotation kit and I have seen many guys install it incorrectly with the openning blocked and their engines do the same thing until the opennings are aligned. The carb simply doesn;t pump fuel.
