RPM sticking sometimes.

[cbrown5385]

I’m having a slight problem I have 86 k10 with a carbureted 350. Every so often when just crushing and pulling up to and intersection the ideal wants to remain high to where I almost have to rev it a little bit to get the ideal back down to its resting spot.
I did it today coming into my drive way I got on it a little bit and the RPMs hung up until I reved it then it settled back down. Any thoughts?

Choke linkage on the carb, throttle cable binding, look and ye shall find???

I'd say choke not adjusted properly. You are getting up on the high idle cam because the choke isn't coming off all the way.
