Doug - thanks for the vote of confidence (something very rare for me in CACC
). I agree with Doug. I would first look at the float and fuel line valve. I had a bad fuel valve in one of my IDAs and it completely flooded the one carb (long story how I found out). Surprisingly didn't really notice it driving.
Best way to check float level is to remove all of the carb cover screws except a couple. Run the car for a few seconds to be sure carb is full of fuel. Shut off car and immediately remove the last two screws, open the cover and actually measure the top edge height of the float. It should be about 5.5 mm above the top of the carb (at least it is 5.5 mm on an IDA, I forget what it is on the IDF). Adjust if necessary and replace cover with the 2 screws. Test again. When done reassemble and enjoy!
