One of the engines I bought has a factory mufler - exhaust collector. I plan to coppy it for my other engines. It is definetly a lahte project.

I don't have digital picture taking abilities at the moment.....

I suggest taking some 400 grit paper and a pencil erasser to rub the paper around all the edges of the ports otherwise your piston may get scratched very soon.

It is pretty neat to have a look in there anyway. You will like how beefy the rod is!

Did you get your Valantine engine that is in your avitar picture to run well? I have one of those on the way too. I hope it runns well 'cause it was pretty expensive.
