Ok, so I just started to have a problem in my '68 nova with a 230CI engine and 2 speed auto tranny (4 door if it matters).

Anyways, I was driving along a while back and when I let off the gas, the engine RPMs didnt drop...If anything they were still climbing, and I had to kick the pedal for the engine speed to drop.
It stopped acting up for a while and I had basically forgotten that had happened until yesterday when it started doing it again, and quite often, sometimes even kicking the pedal didnt help. At this point I parked the car. I figured I was in need of a new accelerator cable, but upon further inspection it looked and felt just fine...

Now Im not a carburator guru at all, but when this happened the choke wasnt stuck on or anything and from what I can tell all the carburator linkages were attached and functioning.

Is there anything on the carb I should take a closer look at, At this point Im sure there is something sticking but I dont know what to go after.
What should I look for???

Thanks in advance.

Welcome to the site.

Besides checking the carb linkage also check the linkage from the carb or intake pivot to the transmission. Also check the motor and transmission mounts.
