Go ahead and use the nonhardening sealer. As a general observation, it is common for engines to idle about 750 rpm when warm and 850 to 1000 rpm when cold. You will get some specific data from other forum participants that are familiar with your car. When you seal the carb mounting leak, you may have to readjust the carb.

Don't tear into the carb yet. Wait until after you fix the vacuum leak. The carb may be fine. No need to go to the dealer to find intake manifold leaks; you already know how to do it with a can of carb cleaner.

More important, when was the timing belt last changed? It is to be replaced every 100,000 miles.

Good luck with your HF. They are a neat car.
