This is what the bottom tranny area looks like on my old Snapper
Snowblower. The silver colored disk is belt coupled to the 5hp engines
power-takeoff shaft. It spins all the time the engine is running. The
rubber disk contacts it when a hand grip is squeezed. The lever in
front slides it left to right changing speed and reverse by contacting
the other side of the disk. Everything you want is already here. This
is a common drive mechanism in the snowblowers here and some
lawnmowers...

A replacement rubber-shod friction drive wheel for my 1990's Toro snowblower cost me only $20. The control mechanism could be made from drilled bar stock. It could also work for parallel shafts and a conical driver, if you can find or make one.
Go karts use a comparable variable speed mechanism with starting clutch.
