weber electric choke question

[offcamber40]

Now that it is cold outside, my 2F runs rich as hell and sputters and bangs blowing black smoke and fouling my plugs until it gets warmed up. It has no problems during the summer months. my question is this: I read somewhere that the electric choke on the weber required a certain voltage, me being the electrical moron that I am, have it running directly off the positive on the battery.. is this the correct voltage or do i need to run it off something else to work properly? Any help would be appreciated.

I've got mine running off the + post of the coil. So I guess it's more like 9 volts.

No problems, but it's only been down to about 38 in the mornings so far. Pedal to the floor once, starts first time every time. It takes a block or two to quit stumbling. It's still not even up to operating temp when my 'commute' is over, but it runs just fine after the stumbling stops.
