Git'n ****ed.
Fired up Cruis'n Rulz! first time this year. Ran fine for about 1 min,
then gas started coming out the float bowl vent on the Rochester
Quadraflush 4M. Rats! Float sunk, I thought. Pulled the carb top. The
float was the foam type, and felt heavy. Cool.
Pulled the carb and went through it. Replaced the float with a brass
type. Set it up, and installed. Ran good for a minute, and as before,
gas started coming out the vent. I thought MAYBE I flubbed the float
setting, so took the top off and rechecked. OK.
So...
Possibly have a bad new needle and seat, But I'm thinking more like
fuel pressure problem now. Does the Mercruiser mechanical FP have a
pressure reg built in? Do they stick sometimes?
Getting tired of pulling the carb top....

I don't know anything about Mercruiser specifically, but MOST (not all,
for the pig pilers!) mechanical fuel pumps on cars are not adjustable,
they are just made to pump 5 or 6 p.s.i. sometimes more (again, not all
for the pig pilers). There are exceptions, like Edlebrock makes high
performance mechanical fuel pumps that are adjustable, used mainly on
racing applications. Like you, I could see a needle/seat being bad and
causing it to run rich or something, but to overflow that much seems to
indicate something else.

Did you check the filter (where the line enters the carb at the front)? On
my Blazer the seal broke and so much crud came in to the float bowl I had to
drain and vacuum. The trash continually jammed the float needle/seat and
caused the same symptom you're describing.
