Hi Guys got this old 3.4 mercury started its idling at 1000 rpm. Want to bring rpm down. Question is how. So far I have removed the throttle cable and
adjusted the idle screw backed it all the way out so the idle stop is not even touching. Still at 1000rpm

It will idle at 1000rpm on a hose as no backpressure....good luck at finding parts if needed.
