Alright, I'm stuck between a rock and a hard place. I have a Cox TD .051 that I purchased new back in '92. Was a lovely little engine and would easily turn 25G. Was wanting to put this on a Sig Hummer, but unfortunately my storage unit was flooded about 3 years ago which included this engine. I wasn't able to get to it and inspect until well after the flood subsided, after which the damage was done. Cyliner, piston, and rod are extensively corroded with rust (in fact, the con-rod broke after trying to loose it up with penetrating oil). I've literally tore apart the internet search engines, looked on here, and spent about 5 hours trying to locate someone who might have what I need. Does anyone out there know where to send me? I'd hate to have to throw this little thing in the rubbish. Thanks in advance for your replies and help. I love this little engine!
