That was my thoughts too, but I just found it odd. Thanks for the reply. I thought a vacuum leak would cause it to stumble and chug... not run with a higher idle. I guess it could be bad gas. I guess I’ll just have to dig into it some more.
Does your car idle differently when parked on streets or driveways that vary in angle?
No need to answer, but there's the answer to the "ride height changing the idle" question.
Very likely a vac hose off, or a hangup in the linkage.
This is assuming the carb is clean and there isn't junk in the idle air ports.
Every once in a great while I will count the turns it takes to bottom out the idle mixture screws and then take them out.
I shoot a little WD40 or whatever into the needle holes and then blast them good a hard with compressed air.
The fluid helps with the air to carry any junk out.
Then put your idle mixture screws back where they were, and if the idle changed you had junk in there and it got blown out.
Then reset your mixture where you want it.
