How long is the choke supposed to stay on? Say on a 65deg evening? Last week, the choke would stay on for the better part of 10 minutes, even while I was driving.

While the choke was ON, my voltmeter was showing the voltage to be steadily decreasing. I think this is because the choke provides a ground when it is not ON. With the choke on, the only way to get the system to charge is to hit 4000rpm to get the alternator to kick on (not good w/ a "cold" engine). If I do rev it, the system jumps right back to 14V.

So is my choke staying on too long, causing this chain reaction? This is the first time I've had this problem because it's been cool out for the first time in a while.

Before this, "bubba" wiring was in effect on my alternator and the choke was not connected. I am certain everything is hooked up correctly now. The carb was rebult about 4500 mi ago.
