Help - Just came back from the shop - plugs, timing trigger, carbs cleaned, fuel system cleaned and went from 20 micron to 10 micron fuel separator - it Idles at 650-700 should be 800 RPM, can I manually adjust it to 800?
Yes. But adjusting idle is best done in the water.
Looking at this picture, your idle adjustment screw will be the one that looks almost hidden behind the hose coming from fuel filter. The one right below the screw with orange lock tight all over it.
Let motor warm up, then turn that screw until the idle raises up to your desired rpm's.\
