I recently acquired a used Zodiac complete with a 1989 Mercury 9.9, it is a recoil start short shaft model. It appears to be in exceptionally great condition. Starts right up first pull and idles wonderfully. Transition to WOT is a little rough and wide open running is a little rough as well. I suspect high speed carburation, old gas, and old plugs to be the issue... I just got the thing so I have yet to decarb it and clean it up right... Anyone else have any ideas as to what it might be? I haven't checked the compression yet but since it starts so effortlessly and idles so well even with the idle knob turned all the way down in gear I suspect the compression is quite good.
Anyhow, my question is can someone please tell me the correct spark plug and gap for this engine, as well as the correct fuel
il mix? Thanks a bunch! I need to pick up a service manual for this engine in the future.
