Re: Building an engine
Welcome to the forum.
Is this a Chinese 2 stroke bicycle engine? Where did you buy it? Was it disassembled when you got it? Some suppliers are now selling engines in parts to get passed current EPA import regulations. I assume this is what you have but we do need more information.
Assembly isn't difficult but you need a certain degree of basic engine knowledge to do it right.
Get back to us with some particulars and we can offer more assistance.
