Default Carb Installation

I am getting ready to install a new carb on my car. It is an electric choke unlike the previous one. It needs to be tied into a key-on 12 V source. My question is what would be the best place to tap into.

Any 12 volt key on source will work. The easiest way to find one is to get a multi-meter and start probing.

I just did a search for "electric choke" and found 264 messages regarding this topic in the classic section alone.

Good luck!

Wire it to the STAT connection on your alternator that way it will onle come on when the engien is running if you wanna listen to the radio just sitting there in the parking lot and you turn your key on to listen to the radio and your electric choke is wired to the ignition you will run your battery down.

No. That will not work. If you actually take the time to read the other threads, you will find out that after-market electric chokes need a full 12 volts to operate correctly. The stator terminal on the alternator will not provide that, the coil will not provide that. As I said before, get a multi-meter and start probing. It really isn't that hard.

I guess you're all right. 9V won't do and 12V constant power is no good either.
Work with a relais if you don't find any other option.

A standardrelais (tell them in part shop/scrapyard what you're up to).

If you look at the wiring diagrams, you will see that you get switched 12 volts at the ignition switch.

what Soaring says should be green/black cable.
I'd still prefer the relais method from the cable that goes to coil as you wouldn't have to run a new cable from ignition switch to carb. If you're using a relais you can always throw a fuse inbetween for the sake of it

Default RE: Carb Installation

on my car
battery 12.5V
voltage at coil when ignition on: 6.5V
voltage at coil when engine running: 10.5V

I'm not sure if the power at coil when engine is running is regulated down or if it's just the fact that the cable is going through 1500 connectors and switches and fuses that are 40 years old. I guess it's the latter. So give it a try with coil. It might work. If it doesn't, then go for a relais that snaps already at 9V. problem solved
