Does anyone happen to know what the setting for the idle mixture screw should be for a 93 4.3L SP with the Nikki 2bbl carb? (Don S - this is a friend's boat with the same power train as mine. What can I say?) I can find the info for just about every other engine/drive/carb combination, but not the 93. Neither the (kneepad) Seloc manual or the shop manual provided by Don S. has that info, at least not that I could find.

It's just a preliminary setting, give 1 1/2 turns out from LIGHTLY seated. Then once it warms up adjust it to the engine.

Don, thanks for the info. I set it, started it up, and she was running better than before. Got it tweaked and she's running right as rain!

Thanks again!
