Ok update on the carburetor. I went through the Holley again and didn’t really find anything off. Main jets are 70 in the front and 85 in the back. Power valve is a 6.5. I installed a 1 inch carb spacer for 3 reasons 1 I wanted to experiment with more plenum volume, 2 I needed to gain some clearance from the choke well on the intake because it was causing the secondary linkage to not open more than half way, and 3 I was buying. New carb gaskets anyway so used this a way to get them.
I did flip the secondary throttle stop screw so it can be accessed from the top (great tip). Reinstalled carb and started vehicle. Same exact issue as before. Only idle at 1800 rpm. Lowering idle while adjusting mixture screw had no effect. I then turned the secondary throttle screw out 1 turn and restarted engine. I was now able to lower idle down to normal idle speed of 800. I tried adjusting idle mixture. Idle mixture screws have no effect. I can turn them all the way in or all the way out. engine still sits and idle sand wont stall. I am thinking it is getting fuel from either a leaking or incorrect for my combo power valve. I feel like me adjusting the secondary throttle stop is a bandaid covering up another issue. On a good note the car runs really well power wise with the 800 on it.
