Anything else happen or get changed? It idles proper at 650-700 when warmed up? A blown canister can cause a high idle, but that normally stays high. Some had this vacuum solenoid valve behind the carb that can blow an open into the PCV system if it isn't working right or is stuck. It should be affected by the engine warming up too. Has anyone been messing around with the vacuum line plumbing or working near any? Mike |

The fix is a clean with carb cleaner spray. Next I would have the engine off and cold and give it two shots on the throttle like you should for a normal start, then open the air filter without starting it to verify the choke is closed. I was thinking electrical due to me misreading your clutch settings and agree the basics should be looked at before messing around. Mike |
