First I want to applogize to the guys that I said I would send some parts to. I still want to get that done I just have been so busy with work and work has been so crappy i have to do it.

Anyhow on the bad threads. i think the best idea for repair is to use alumiweld. it is kind of an aluninum brazing rod. I found it at harbor frieght and have tried it for welding together mufflers. it melts at somewhere around 750 degrees so it shouldnt ruin a cylinder. It uses a propane torch to weld with it.i think it has great potential to fill the holes to be re drilled and tapped. I would even be willing to try and do this repair for you if you like. I also have a tig welder and could go that route but i think the alumiweld would work good.

Unfortunatlly it may be next winter before I can get back to testing on this engine. It may be a good thing though as i really need the work right now lol.
