If you hear more air from the bottom one then sounds like it may be not set
the same as the others. Reverify it is in sync.
As for the idle screw setting - not sure on this one. I would start at
about 1 1/2 and adjust from there.
Did you accidently adjust all 3? Could you not take a reading off of one of
the other carbs?

Yeah, I was a dumbass. My wife was distracting me and I wasn't thinking
and started backing out the screws. When I figured I had 'em out far
enough I tried to take off the airbox. Thats when I noticed the OTHER
screws on the backside of the airbox. I turned 'em in to 'stop' then
backed 'em out two full turns each. At this point I instructed my pesky
woman to go online to iBoat and order the Service Manual, which she
happily did. I await it's arrival.

The engine idles.

The bottom carb makes a fluttering sound, unlike the other two, no
matter how I adjust it. I'm afraid I'm hearing a valve or something
through the carb (and hose).


We took the 1984 Trophy out for our shakedown cruise on the Fourth.
It ran crappy at first, wouldn't get up on plane. But after a couple
minutes it suddenly "woke up" and hustled around fine. We cruised across
the lake just seeing the sights. I stopped to point out something, and
it ran crappy again after that. We limped back to the ramp and went
home. I'm assuming carb troubles because I know the boat sat for a year
before I bought it. Either that or gas vent troubles or one plug was
fouled. I dunno. I await that manual!
