So I fired up the motor after the HG change without adjusting the carb (leaving it how it was tuned when the car was running good before). The car idled with 16 degrees of base timing previously.
This time, the car needed at least 20 degrees to idle. So I had to turn the screws in a full turn on both sides to open up the butterflys. The motor has 1/2 a point less compress. and more lift than it did, could this account for this? Could a vacuum leak account for this?

Also, I noticed the motor takes longer to settle back to idle speed after I rev it up.
