Well I thought I would write back and keep this discussion alive. Just an update, I recently acquired a Roto 25 gas engine for this Big Rascal. I have not run the engine yet, but from just the looks of it, the craftsmanship is simply amazing. Now that I have the engine, I need some serious advice from all you experts out there. I am trying to figure out as to where I am going to mount the ignition & ignition battery as well as how to run the spark plug wire through the fire wall. Any and all ideas are welcome! The thought of still using a G-26 is still my preferred option, but I have run into the problem of 1.)Muffler 2.)Backplate 3.)Mounting. I was thinking of using a B&B Header for the exhaust. Please if there are any more pictures, fell free to post them. Thanks again to you all.
