I am having idling trouble with BB 2stk stock up jetted carb. It has over 2000 miles and its just a little rich. It started when I ran it hard then came to a stop at a stop light. It would idle fast then you hit the gas once and it would idle. I have ran sea foam in it a few times. Changed the chock no cables binding. But is getting worse even now at slow speeds. I shut the key off once at high idle and it stayed running. I am running a BPR7HS and squish is 1.2. Any ideals??

Also, if it's running lean or hot for whatever reason it might idle high after WOT.

Still need to reset air mixture and idle.
