Does anyone have any details of the Honda GX31 conversion? I'm doing one right now, I have changed the carb to an adjustable WYK which has improved the revving no end but I would need a retract servo to move the throttle! I believe there is someone using one in a DR1, any details/vid etc? I would like to change my carb to a normal Walbro rather than the WYK type which would eliminate the return spring problem.
