Good afternoon everyone. Hope all is well. I have been going somewhat crazy with carb issues. I have a QJ which was rebuilt by Ken over at everyday performance. After the motor was built and an attempt to tune, the mechanic said there was a vacuum leak and throttle shaft play. I sent back to carb to Ken and he did not find any vacuum leak or throttle shaft play. The calibration is at 73 jets 44b rods and CF secondary rods. The only thing he saw was that my throttle at idle was very open. To counter this, he installed idle bypass air by drilling two holes underside of the baseplate in order to allow for additional air into the engine at idle. Received the carb and have attempted to use several gaskets to see if that was the issue, but remains the same. The car is very hard to idle while cold having uneven idle where engine just idles and reving on its own. Once the car is warmed up, I attempt to tune via idle screws nothing occurs. I have closed the idle screws all the way and has no effect on the engine. As for gaskets, I have used the 1/4 thick FelPro 1905 (this is what was installed by scotty) as well as what was recommended by quadrajet parts. Currently gasket setup is 1. Smiley face on intake 2. Metal Shim 3. Base Gasket part # 1714 from quadrajet parts on carb Same issue. I know back 2018, I was on the hunt for the proper gasket before engine was rebuilt, but for the life of me I cannot find what I purchased back then. I do recall when I bought the car, it had a 1/4 gasket, and I was able tune the idle. Suggestions? Recommendations? I am using the stock 1967 intake manifold.
