HP .61 Motor

Postby ForeverHero » Fri Apr 28, 2006 1:29 pm

I was given an old HP .61 engine that was in a helicopter frame for the last twenty some years. Unfortunately, I did not have a muffler attached to it when it was given to me. I would like to use this motor but I cannot find a muffler to fit it. There are no attachment holes so it must have used a 'strap-type- muffler. I would apreciate any help that you guys could provide.
