Hi, I’m not sure if I have one issue or two but the title says it all. I had a surging issue years ago and posted here and got great and accurate help (it was the carb). After much delay I just had the carb rebuilt and it’s now starting like a dream and runs perfect in the water.. until I shut it off (it’s always had this issue but always started, I swam my family to the ramp yesterday). It’s also slowly stalling at idle unless I catch it and bring up the rpms, and then I can’t get it started.
My first idea was check the idle and air mixture screw but then realized with the T5 I need to ground the Purp/wt wire to do this. Do I just disconnect it and ground the wire coming off the T5 box? I’m wondering if my old school shop rebuilt it great but didn’t set the idle properly with the T5? Obviously not since they never put it in the water.
The only manual I can find describing the procedure only mentions the 4.3 Merc. I have a 96 5.7 Serial number 0F605391 W/ 2 Barrel MerCarb part number 807312 Date stamp is 5402.

If I head on on the water what should I be doing and checking first? I know timing should be checked but carb adjustments could be easier and may solve this I hope. I’ll check to see if it will start WOT and watch for gas entering the carb in case this is a flooded situation on shutdown.
Thanks
Also, I’ve done a lot of research on the hot start issue and read a lot about vapor lock and other hot fuel issues but I’m still narrowing it down.
