How well do Weber carbs perform in the winter? I'm mainly concerned with the cranking ability of the dual Webers (40mm, 44mm) on those cold 20 degree (F) mornings. How well does the car idle and accelerate from a stop since the Webers have no choke mechanism? I'll be driving my car "everyday" and don't want to have to worry about frequent tuning and balancing.

I dont think you will have a problem. Switch on the car and drive it, it should idle properly after the first minute. Otherwise, set your idle speed up a little. What else you could do is richen up the fuel ratio a little, after all, that is what a choke does (the choke just does it more!). Good luck, and best wishes for winter, my summer is starting hahaha Image

You will have a b*tch of a time getting that thing started on a twenty degree morning (lots of pumping). Once it is warmed up, it should run fine.

Years ago I had a Baja Bug with Kadrons. More than once I had to use deicer on the linkage and it allways started. I had to play with the throttle to keep it running for the first couple of minutes. After that "Jack" was ready to Rip! Btw I learned the deicer trick after breaking the cable using a heavy foot to clear the ice from the linkage.

I have run VW's in -30 degree weather. I'd suggest a warm-air box with feed at temps below 35 degrees. Otherwise, you will get a lot of wear from unburned fuel wash, and carburetor icing on cold, humid days.

Where do you think all that 'extra-rich' mixture goes? Modern carburetor cars give warm air at about 50 degrees for emmision reasons, but the cold air (down to 35) DOES give you better performance once the engine is warmed up. I agree, duals ARE better, as above.

Can you take warm air off the top of the heat exchanger, by removing the brass bellows, like you can with a Type III? It worked great on my 'mountainback'. (240,000 miles)
