Default Re: Staton crankshift kit with Honda GXH50 motor comparison to Subura motor setup.

Well, the build has been going along just fine with the installation of the engine/gearbox, some small modifications to get these items tucked forward and as low as possible in order to minimize the high outboard appearance of the setup...............then ran into a major road block..........upon completing the rough installation of the engine/gearbox I decided to run a quick in-shop drive train test to see if everything was tracking and running properly, it was not.

Somehow the complex front chainring/freewheel assembly is not freewheeling for the motor drive side, causing 8 pounds (as measured with a postal scale) of drag force being transfered to the pedal side drive making the pedals rotate with the motor ring. The pedal side freewheel works just fine with zero drag.

Anybody experience this same problem and know of what I should look for to correct this situation?

Photos to follow................Don
