i have a quadrajet carb and it was just rebuilt 2 months ago it was the first thing we did.

After the interuuprter switch---things on carb to check--even though just gone thru--crap happens---float level(should have a brass float for sure-if not --put on in) Accelerator pump( not sticking and not returning to the up position., and main rods to make sure they have not come lose.

Maybe a bad guess, but what about water intrusion into the pistons and burning them away. I know my Evinrude is an outboard, but that is what happened to mine. Same scenario, runs good on land but put in water on load and sputters out. Turns out I lost 1,3 & 6.
