so I have stock 50cc two-stroke and I had done some porting work and all that and I had also sanded down the head to get higher compression because later I would like to put reed valves and the such on it but right now it only runs on the choke on and it also won't have any power behind it I do plan on buying a high compression head when I have to money could it be compression leak not enough spark to much gas or to lean i don't thing my not carb is clogged seeing as I just cleaned it not to long ago
