So I traded a minibike frame for 6-7 engines and all of the parts for them (except for cams) Not all of them are the same, but they are very similar, so how bad would it be if I were to just cobble together an engine with the parts and tried to start it. I bought a cam and mikuni from ebay, so just wondering whats the worst that can happen. Also how can I start the engine without a pullstart? Thanks
