If floats are right and it's still pig rich you've probably got a blown power valve.

As for the assembly under the acc nozzles sometimes it's there and sometimes not.

Still cant get this thing to idle, and still seems like it's running way to rich. I have new power valves, needle and seats, spark plugs, and all new gaskets in it now.

What size accelerator pump nozzle and what size jets would be in the ball park for this motor? 1993 454 that is stock other than an aluminum eldelbrock intake and this carb.

Maybe lets step back a bit, being this is a new to you boat

How about a compression test?

EDIT: also if fuel pressure is to high it will flood

Have not done compression test yet. I'll do a fuel pressure test shortly.

Primary jets are marked 88, quick research shows this is a little high?

8-9 psi of fuel pressure going into the carb, also seems a little high?

List number will tell you correct jets. My guess.. 75-78 for primary Just a guess tho.

Post the list number off the air horn please.
curious exactly what you have

If your gauge is accurate then 8 and higher is a bit to high

its a little high but needle and seat should be holding,I've seen them hold all the way up to 13psi.have you switched carbs yet?
