If you want to piece a motor to gether get the CY F270 four bolt bottom end, a Zenoah 25.4cc (G270) or 28.5(G290) topend and you can use all your old parts from your stock motor(Coil, shroud, carb, airfilter setup, flywheel, and crank) You can have an engine that will last you many many gallons and make great power for cheap. Give me a few and I'll get some part numbers and links for you.
Here's the parts:
