You are correct. I'm having a hard time with the throttle setup. I found temporary solution, but it's not perfect.looks good and simple from the video, thats what i like to see!
it looks like you dont have a clutch setup, and the roller is always enguaged.
i suggest a lift-clutch to pick the engine off the wheel so you can coast and idle the engine,
also, i didnt see a throttle. or was it just me?
