Default Re: Bigger studs on my second engine.

The castings are very ruff on these motors so most of the time there are flanges of metal from poor casting in the ports so we like to clean that stuff out. We use the dremel with the right size grinding weels to clean stuff like that up. Youll see what I mean its all been gone over many times here just search and youll find it all out.
