    Yes BUT. Why would you want to use Propane? Compressed Air, No Spark Plug, No cost for fuel etc. I feel bad now. I think I have hijacked this Great Tandem Build page. Sorry, I did not intend to do that.
    I just brought it up since this Build is done so well I thought you may want to try a Compressed air Engine.

    I think the electric start GX 160 will work just fine because that is the engine I have to work with and it's brand new. It's guaranteed to work and I've already installed a billet rod and a modified cam in it ;)

    This is taking forever.......need more hours in the day laff This always happens when you try to work on 2 or 3 bikes at a time, and work just gets in the way and slows the progress. Workin' 2 jobs at times just makes it worse, I wanna retire...

    That is one seriously nice looking tandem Scotto. The front fork conversion looks really great.

    For some reason when ever I see a motorised tandem I'm reminded of France.

    OK, back to this build as I finally finished the 79cc aluminum bike for one of my sons. Will be putting in a full day tomorrow and hope to get as much done as possible, which could be a lot..or? Can't wait to finish this one again as it's twice the fun of a single seater ;)

    Really didn't get much done today as the weather was incredible.......warm and sunny so I took the 99cc out on a nice long test ride and had a blast. Running the 19mm carb and larger intake manifold, I was pushing 7,200rpm a lot with no ill effects. The bike is running great!

    I did play with the tandem a bit however.....put a few cogs on to drive the rear wheel with the engine and had a gear ratio of 1.980:1. Shut the engine down and the rear wheel was still spinning at a bazillion miles per hour.......scary yet impressive.

    Progress in the works........
