high idle
When my engine fully warms up, it will idle around 700-750 rpms. If I kick the pedal like knocking off the fast idle, it will drop down to 500 rpms. It will jump back up the second I touch the gas. The choke fully opens, and there are no vacuum leaks. When the engine is running around 700 rpms, the throttle lever does appear to be against the curb idle screw. Any ideas what causes this? When I start it up when it's warm, say after 15 minutes of sitting after it was last run, it fires up and idles at 500 rpm again.
I know it sounds confusing, but if there are any ideas let me know
