my bro removed the carb from out 82 ski nautique and had a guy rebuild it for us, using the rebuild kit from skidim. The guy has built many engines and carbs so i assumed he knew what he was doing. Well his missed something, because now the boat will crank and run perfect above 12-1500 rpm, but WILL NOT IDLE for anything If you try to let it run below 1200 RPM it dies. What i thing are the "booster venturis" seem to be dumping fuel down on top of the butterflies. I took the float bowls off and the float height appears to be right or very close according to some info I got off of the holley website.
We've moved the idle adjust screws every which way but all the way out and it doesn't matter. (of course, because there is so much raw fuel just being dumped in it.
So what could the guy that built the carb done/missed that would cause this.
The choke is operating properly and we checked everything we could find for vacuum leaks.
We also too the carb off of my brothers supra and the boat cranked, idled, and ran great. There was of course no raw gas visible from the top being dumped down into the carb from the "booster venturis" (if I'm calling the right thing?)
any ideas or anything i'm not an expert buy any means but this has me baffled. any help is greatly appreciated.
