Just a thought..... when I was going to put the little 2 cycle in the tot rod, my plan was to just use pulleys and a loose belt. Then use a pedal operated tensioner pulley for the kids to engage and disengage the engine (placed where a gas pedal would be), and a second pedal for the brake.

You could either set the engine speed at the engine or if you trust the kids enough let them adjust it with a hand throttle on the dash.
