I have a 95 120 sport jet. Compression good. cleaned the carbs 3 times put a rebuild kit in one. Replaced fuel lines. Fuel dumps out the front of both the carbs at cranking speed. Removed carbs and pumped fuel to them with a ball. Seats and float held till it was hard. What next??? Iam getting a fuel pump rebuild kit but iam pretty much reaching for straws here. I also unhooked the auto enrichner to see if that did anything with no luck. Any ideas please
