    there is a reason they number them, gets pretty easy if you remember 1&4 fire simultaneously and 2&3 do the same.

      yep, but that's me... I have the tendency to look like a dufus... but that's the only way I learn. That said, I never heard that before (1&4 and 2&3 firing at same time); I'll remember that.

      After seeing how boat places and friends with boats said the motor was "totaled" and non-repairable, I'm just happy to get it back up and going good. Hell, may only last one more year, but learned a ton.

      Last question: My idle sounds a little high and I have to admit I mess with the pilot/pivot screw; is that what I should put back to where it originally was? (especially since I read recently to not ever touch it)

        the idle adjust is on #4 carb. do NOT jack with 1,2 or 3.
        the a/f screws usually you can run them in and back out about 3 turns for a starting point.
        you probably should have the carbs set by a shop with a 4 channel manometer.

          Congrates on getting it running again!! $hit happens!

          So I guess the issue with the head wasn't that bad if its running pretty much normal again?
