Hello all! New to this forum and just bought a used McKee Craft bowrider. My issue, to start, was the boat only went trolling speed when full throttle. Found there was an issue with the fuel line leaking at the coupler that couples the fuel line from the gas hand pump to the short fuel line going into engine. I fixed that. I noticed the air/fuel screws on carburetor (this has a carb tree. 3 stacked) were possibly out of whack. One screw was 1 1/2 turns from seating, one was 14 turns from seating and the other was like 5 turns from seating. I got those in sync while using muffs at home. I was ready to put it in the water to adjusted them with a load on the prop but before I left, I fired the engine up on the muffs. I noticed gas slowly leaking out the open hole on the carb, just to the left of the air/fuel screw (see attached pic). Just to test, I turned all air/fuel screws on the carb clockwise and lightly seated them. I thought the engine would choke out but it didn't?!? It may have been running higher RPMs when all 3 were closed. So, why didn't the engine choke out with all 3 air/fuel screws closed? Also, why is gas trickling out of the open hole next to the air/fuel screw? Thank you for helping
