So after a week of running smooth I seem to have developed more problems! My engine starts properly from cold and settles on an idle of about 775 RPM with a very minute bit of hunting to start off. However, after some time running the idle begins to stick around 1500 rpm to 2000 rpm. If I manually depress the idle microswitch then my revs _sometimes_ drop back to the expected 775 RPM, however sometimes engaging the microswitch appears to do nothing.
It appears to only get worse the warmer the engine gets, to the point where engaging the microswitch does nothing to help the engine idle.
I assume I'll need to take the air filter assembly off to get a better look, but can anyone advise as to what the issue may be? Bad micro-switch or a bad grounding would be my inclination, but I'm not sure if there is something else obvious that I am unaware of...
