    Can the little 23 cc engine be set up for direct drive without a clutch so that it starts when you pedal and shuts down when you stop?

    R/S makes two engines in the EHO series, 25 and 35 cc. The 35cc is the more commonly used but I have known a couple of people who use the smaller motor.

    I imagine you can set them up without a clutch. I haven't done it with a Robin but have a Mitsubishi 43cc direct drive. The shoes are removed and a steel plate needs to be fashioned and bolted in place of the shoes with a drive shaft fixed onto the center on the plate. I know of no after market parts available though so that leaves making your own.

    Contact Dimension Edge online. They offer their engines like how you want them to run.:idea:

    Not sure of the shaft size, but if you remove the clutch, you can thread on
    on a textured aluminum bike foot peg,( see ebay),to the shaft. these are
    3/8" i.d., 26 thread. if shaft is 1/4" , snip a small piece of sheet alum., roll
    it around a screw driver, and insert into the peg as a bushing and thread it
    onto the shaft,( pop can aluminum works.) To mount your eng. see my
