My 87 YJ 4.2L always idled too fast. The experts all said it was a vacuum leak issue. They recommended a rebuild. I opted for a new carb. Same exact unit but is a clone. There were no instructions. I put the fuel and air screws the same as the old carb. Left and right screws at 3 turns out. I'm getting fuel to the carb but no gas through the carb. Someone said to look down the throat and look for gas squirt while turning the throttle. Nothing. What should I do to fix this? I still have the working old carb to swap parts if needed. Any ideas or words of wisdom is appreciated.
