Honda Express Back wheel spins like crazy in idle

When I finally get my express to run the back wheel spins incredibly fast. The whole moped begins to shake on the kickstand. Twisting the throttle makes the engine rev faster but the wheel continues to accelerate on its own. After a few minutes the whole thing stops.

Any suggestions on how to fix this?

Turn in the idle screw which is the top screw facing the front of the bike on the carb. This will slow down the idle, it should spin slowly

what he said- idle is too high.

Re: Honda Express Back wheel spins like crazy in i

I have turned the idle screw all the way out and it is still spinning much too fast. What else could it be?

your engine has a vaccum leak. possibly the crank seals. my bike did that same thing.

Re: Honda Express Back wheel spins like crazy in i

Where would the crank seals be?
