I can't quite figure out if my auto choke is actually working or not. I recently installed a weber dgv carb and got rid of all the emissions bs by plugging holes etc. It idles great, but when started it slowly builds up from around 500rpm to 750, and if I give it gas when I first start it, it will die and then I have to start it again. I notice that the brat had a fuel return line on the stock carb but this weber does not, but seems like it could have a return line installed. I hooked the auto choke power cable to where the stock one was hooked up, but of course its only one wire. Heres some posted pics of what the current situation looks like.

 

 

 

Check the fuse for the choke. You might have grounded the circuit out during the swap.

 

If the fuse is good, you need to find yourself a multimeter and start testing leads. I cannot remember which went where. I do seam to remember that the blue lead WAS for the choke.

 

if you ARE getting power to the choke, either the choke is bad, or simple needs to be adjusted.

I got 12v from the wires, how would u go about adjusting the choke? I thought its automatic lol, im noob to cars btw. I just pick up manuals and grasp it for what I need to do somehow.

Before you start the car, push the gas pedal all the way to the floor and release. This sets the choke for a cold start.

Automatic means it releases when it warms up.

Are you giving the gas pedal a pump before starting it? If the choke is too tight and you don't pump the pedal(which resets the choke mechinism when cold), than it may start, but when you hit the petal the choke plates will slam shut and suffocate the motor. These motors don't really require to much choking, especially in the summer. Set the choke so it restricts 1/2 to 1/3 of the openings in the carb when its cold, and adjust from there...I make a mark on the choke housing to indicate how far I've adjusted it and also mark an arrow to show which way is tighter, then I leave it a little firm enough to not move, but loose enough that if you grab a firm hold of it, you can twist it. As you go to work, errands etc., you can quickly adjust it to get it dialed in. Don't forget to tighten all the screws when you find the right setting.
