To be 100% honest. The whole engine in the jawa is too far gone to fix. There was water sitting in the engine for quite some time that all the parts but a handful are saveable. Replacement engine cost to have shipped to me as I can find them in state side but I live in Canada. So shipping over doubles the price then the conversion is making any engine I can find thats original not worth it to me cost wise. The chain saw I bought for less then $15 cad. I’m not planning on doing anything to convert the frame from original as much as I can do if I do eventually come across a motor in Canada for a reasonable price I’ll totally buy it and put it in instead. But for the mean time I’d like to have a running project thats different then others.
