I alredy ordered a 66cc china girl. 32mm intake and 38mm crank. I hope it's a good increase in power. I'm not exactly "slim".
yes very lean makes uncontrollable high idle. Leaving the muffler off is just a really bad idea. Both of these most likely caused the chrome being destroyed. Good luck with the new engine.I'll check the seal under the magneto. But- can a very lean mixture affect idle?
I had the muffler off and didn't re-jet my carb.
I think a higher air flow is what lead to the death of your last motor . Maybe just stick to figuring out stock problems before you start introducing new ones.I know it works- I'm looking for better ones for higher air flow
