Carbed 502/502HP fueling issues on 1996 Baja 272 Islander

Not to side track this thread but offer information, I run that spacer and wide band setup continuously and have been doing so for 3 years (year round boating).

That's one good experience this way...anyway.
Just relaying info...not that I would run stock exhaust on one myself.

Ouch ! Did you have short risers because of Silent Choice or etc ?

Has the cam been verified to actually be the ZZ502 cam? If all is right with that 502, with the ZZ cam I'd think the engine should spin a 23 in. prop close to 59-6K. My ZZ502 spun a labbed 25 to 55-56K pretty easily with a decent chop. If it were me think I'd have a compression and leak down done, and check valve springs, along with fuel delivery. What intake is on the engine? And what ignition system?

So I put the mech pump back on and got a strong continuous 8psi in to that baby. It even idled completely different and I had to reset the floats and other adjustments. No dip on psi when I blipped the throttle so I'm pretty upbeat that this was the issue.
The electric pump was mounted 14" above the floor, so it had even a much further reach down to the tank pick up. From what I now understand electric fuel pumps are not fond of being above the pick up level at all, much less nearly 2 feet.
So talk to me about exhaust, and what I need. This is what I have now.

Am I halucenating or is the carburetor on backwards ?
