After replacing my valve cover last weekend I noticed the vacume hoses into and out of the vacume resevoir were disconnected and my electric choke was unplugged. I fixed the vacume line and plugged in the choke. I figured I'd re-tune the carb (BBD) since I now had a functioning choke and sol-vac (so I thought).
Here is what I came up with:
Fast idle set to 1600 RPM- no problem
Curb Idle set to 700RPM- no problem
Sol Vac vacume idle- couldn't get this set since the vacume actuator wouldn't pop out and hold when I disconnected/plugged the vacume line.
Sol Vac Electric idle- couldn't set because of the problem with the above vacume idle.
I'm not really concerned with the sol-vac adjustments (should I be?). I'd be pretty happy with a functioning choke and good curb idle, which I sort of have.
Here is my problem though, intermittetly once the motor is fully warm the choke will kick onto the fast-idle cam. Playing with it last night it seemed pretty random. The chock seems to work fine when cold. Any ideas?
Lastly, how long should it take for my choke to kick down? It seems to take over 5 minutes to warm up enough to get it off of fast idle. Think my thermostat is bad?
By the way this is on an '84 258 w/Carter BBD
