Here's a video just to give you a better sense of how this propane generator works.
Also, I still need a muffler for the generator. The original would have been a flat rectangular one. Any of the original parts for this generator get expensive quick. The exhaust manifold tube on the generator is a 1" round pipe.
What do you guys think of me getting a plain riding lawn mower muffler and attaching it with a u-bolt? I should be able to find a muffler from a mower of similar engine size. I would know how to size a muffler otherwise.
