I'm hoping someone can explain a few things about this: I've replace
the plugs, rebuilt all 3 carbs, cleaned fuel pump and changed lower
unit oil...
Now, today I fine tuned the low speed jets to where it stopped
bucking and smoothed out. I don't know what the intermediate oriface
( small brass screw at top of carb ) is for or where to set it! Also,
what should I watch for to avoid a lean condition? I've adjusted the
metal linkage off the 3 carbs so that the rod touches the black
plastic throttle plate, not sure if I needed to do that or not though,
does this give it too much air?
Any advise about fine tuning will be a huge help since this is my
first outboard... Tach will go to 5.5 now and runs fast and smooth on
the water, I just want to be sure it's adjusted and running safely
( no lean conditions )- Thanks!

I meant to ask, does anyone know a good source for OMC keys? I need a
spare #75. I found 1 site, but they're $21 a piece and you have to buy
2!!! A bit much for a key! I've checked the hardware store, they can;t
make them, so what do you do when you need new keys??

any authorized dealer has them or can order them

Is anyone familiar with these engines? I'd really like to know what to
set the brass screw at on the carbs! I've checked the plugs after each
run and they're tan with a little oil residue on the metal, is that
ok? With all the rebuild and cleaning I've done, I just want to make
sure it's not running lean. It sounds smooth and quiet and I can get
the tach to about 5.5 at WOT.
