I got this Yardman mower with a tecumseh OHV, OVRM120 engine. The flywheel key is broken, the iron counterweight in the flywheel has become dislodged and destroyed 4 fins. I was looking for a replacement but I can't spend the $100 being asked just for the flywheel. The broken parts of the fin were retrieved and I was thinking about repairing it. It is made of some kind of alumina alloy. I have tried using that stuff off ebay that is made for this repair but it is hard for a backyard guy like me to use. I was thinking of hard solder - the thick non resined stuff. I thought I'd ask what you guys think. Would this work on alloy?
