Alright, got the photos up from before. They lost their file names though. No big deal though.

Had some time to work today, and I focused on the replacement carb I picked up from Ross. I had previously completely disassembled it and cleaned every component. It already been rebuilt at some point in the past, and those rebuild components were still in good condition. The threads on the heat riser tub were cross-threaded, so I corrected that. Then removed the original carb and installed the new one. Put some fuel in the float bowl and car started right up. However, it was somewhat rough, and died after a few minutes. Started it up again, was a bit better, but then died again. Tons of smoke, no oil smell...just super rich.

After it died the second time I saw that there was gas dripping out from the throttle plate shaft bushing. Looking down the throat showed that it was super wet inside the carb. My guess is the float either has a hole, or the needle and seat are bad.

I knew that the original carb worked, and it had brand new rebuild parts on it. So I opened them both up and swapped the float and needle/seat from the original carb into the new carb. Reassembled everything and installed the new carb back into the car. Car started right up and seems to work fine. The choke plate opens up slowly when getting warm, though never reached fully open. Not sure how this normally acts. Accelerator pump seems to work better.

I noticed that the car has a hard time returning to normal idle after taking my foot off the gas. It did this before I swapped carbs. I have to manually move the gas pedal to get the idle back to normal....it sticks high. Problem in the throttle linkage? Sticking pedal? Should I lube the throttle plate shaft on the carb?
