Well I have got the boat in the water after a total rebuild of engine and boat. Now for the sea trails. The original carb (Holley 750 mech sec,) wouldn't let the engine idle, it would run lean. I borrowed a 750 Demon from my son and now the boat idles and ran nice for the first 3 or 4 miles of use at low to mid speed. Now at 1500 rpm or so sustained speed, the primary carb bowl goes dry. (sight glass). We thought the fuel pump (that was on the boat when I got it) was weak, so we changed it to an airtex pump that was larger. Same thing. The front bowl goes dry. This carb gave my son no trouble while on his blown 400 sbc. I was thinking that the float might be sticking at the top, but with the engine vibration could it happen?
