I have a 1976 6-cyl inline 115 hp merc outboard that refuses to start
without a squirt of gas in any one of its carbs. We have had the
engine rebuilt with new pistions and rings. The fuel pump is working
fine. We have taken it to a local dealer/repair shop, and they have
informed us that they can't fix the problem; though, they still
charged us 300 some odd dollars. Does anyone out there have any ideas
that might be able to help? Thanks!

Starting procedure is likely the problem.

You gotta nearly flood them to start them - SOP.

Make sure the motor is trimmed all the way in (down).
Make sure the warm-up lever or fast idle thingie is working. Pump the ball
a little harder than needed - to force a bit of gas past the needle seats.
Advance the warm up lever all the way.

Crank the engine with the choke applied the *entire* time you are cranking.
Once it finally catches, back off on the warm-up lever and warm it up at
2000 or less. DON'T let it rev up hight in neutral after it catched.

As crazy as this sounds, it is exactly the way to start these 'towers of
power". The problem is the size of the holes in the choke plates and one
of these days I'm gonna solder them shut to see if that doesn't cure it
on this (and many other older) Merc models.

Choke plates are plastic on the towers. (and I think solid)

The throttle butterflys have holes.

Hey, thanks, guys. I'll pass this along to my Dad. He has
the boat down on Johnathon Creek. He says that the engine will start
within an hour after having run it for a bit; but, it won't start
cold. The folks at the repair shop were clueless (go figure).

Regards

Look for pin holes or other air leaks into the fuel line, primer bulb,
etc. It sounds like the fuel is draining back down the line after
sitting for a while. Ordinarily, you still have to choke and sometimes
prime, by pumping the bulb, on a cold carburated engine.
