Sorry to report there is a cylinder crack in my 6HP Straubel. I have used this engine extensively for the past 15 years. The crack is low, around the ports. I will try to repair but if there is anyone who has one of these engines they will part with, please let me know.
Any advice on welding the cylinder? I may need to have a new piston made. Any recommended sources?

Is it a freeze crack or salt water crack? Being from Milwaukee I would guess freeze crack. Do you expect you will need a new piston because of wear or because of distortion from welding? Did you ever hear of metal stitching? Any pictures of the damaged area?

I tried to email you but it was rejected, what is your current address?

Hi Dick and Keith,
My email is veloce192 at sbcglobal dot net. I disassembled the engine and the news isn't as bad as I thought. The cylinder has a small crack in the area adjacent to the exhaust port. I was able to remove the piston and it seems fine. My thought on a new piston was that I will need to re-bore after welding the crack. The piston weighs a ton! Would an aluminum piston have less vibration? Where would I get a piston made? I will take the engine to a cast iron repair facility soon. Metal stitching would be difficult on the interior of the cylinder.
Thanks for any advice.
