Title: Adjusting my new Carb
Post by: SlowBug on June 09, 2010, 11:30:26 PM

I am having some troubles with my new carb, its running perfectly except that it idles extremely high as the choke is always open.

It does not spring back when the bugs warmed up.

I have the wire currently connected to A (see photo) but there another connection on the other side of the carb (B.) where the wire can connect to - exact place as the stock carb, but when the wire is connected to that, it does not hold idle at all and motors just shuts off.

Here is a pic for reference:

Here is the carb I got:

and it's 1200cc 63 bug

Any help is greatly appreciated.

If you mean this connection it has to get 12V when the key is on or the choke will never shut off. If the engine instantly dies when you connect it either the it's shorted internally or your wiring is weak.

are you disconecting A to hook up B? they both need to be connected choke and idle cut off jet solenoid to the same circuit  (+) side coil

Would it have anything to do with using a carb with 12V choke if the car is still a 6v system?

Sorry can you just explain how they need to be both connected again?

But yes, nothing is connecting to B, only wire going to the carb is at B, and it runs fine just idles high as hell all the time.

I edited the photo as there was a reference mistake.

so your car is 6 volt? youcan buy a 6v choke coil https://www.cip1.ca/ProductDetails.asp?ProductCode=VWC%2D113%2D129%2D191%2DH or take the 6 volt parts off your old carb some older carbs have a jet that screws in where the solenoid goes ( not electric) http://www.vw-resource.com/carb_41.html#general

pretty positive my bug is 6v, but I just checked my old carb and it has a 12v choke coil.

Now I am extremely confused, because it ran decent before just took a long time to hold a steady idle thats why I got a new carb.

So confused.

try hooking A+B up splice another wire on to the one you have
