Electric choke hookup

Hey folks,
this isn't tractor related, but the principal should be the same.
I bought a used ATV that has startup and idle problems. Get it started the first time and it's fine the rest of the day (just doesn't idle so good). I cleaned and adjusted the carb to get it as best as possible, but, as I couldn't find individual parts, it needs a new carb. The original carb costs more than I paid for the quad to begin with, so I ebayed it and found a new (rebuilt?) one for the same CC and inlet/outlet measurements.

The new carb has electric choke though, and I don't know how to hook it up.
It's got a plug w/ 3 wires (yellow, green, and green/black). The yellow and green go into the carb (choke) and the green/black has a female plug on it.
Does this sound familiar enough for someone to tell me how to make things work?

Thanks, Dave
 
Use a multimeter and find which pair of two wires are the choke circuit on the carb.
Then find the pair of live and return wires on the atv wiring harness.
 
Thanks. I see which two wires go into the carb. The ATV has a manual choke, I need to figure how to wire the electric one.

(quoted from post at 05:30:10 10/21/08) Probably from any wire that goes live after the engine starts.

I'm a little thickheaded here. Does that mean that the choke is on automatically until the engine starts and the power takes it off so the carb runs normal?
If that's the case, could I just, in the worst case, put a switch to flip to disengage the choke?

Thanks again,


Dave
 
yes
Easier to just wire the choke direct to some circuit that livens up after the engine starts. A switch is not practical.
The coil heats when energized and slowly swings the choke blade open.

thanks! I did, but the forum wasn't very active and I couldn't find my brand (Chinese copy of a Yamaha Bruin).
Anyway, with the attitude of "it'll work, or I'll just keep using ether", I took the choke module out and hooked it up across a battery to see what happens. Now, I understand how it works and am OK.
Did I mention I was a little thick headed?

Thanks folks.
