John Muir in his book "How To Keep Your Volkswagon Alive" has some strong opinions about automatic chokes, so much that he would not tell you how to adjust one but only how to disarm them. What are your feelings in this subject. Agree or disagree. Just curious...Breck Evil or Very Mad Twisted Evil

I followed his advice on my original 1300cc on Hugo and disarmed it. It was a PITA. Always had webers after that, never had a choke on the car. Haven't missed having one.

Unless your car is parked in a temperature controlled garage, how do you not have one?

No chokes necessary on a set of tuned 2bbl carbs.

They are the natural progression, come to the dark side.

Darth Vader had dual 48's on his tie fighter... Shocked

According to John a well tuned vw should idle at start without a choke. He states that by the time he rolls a ciggy and gets it drawing good ( about 3-5 mins) your vw should be warm and ready to roll. I always let my bug warm up for at least 5 mins b4 I drive. John was from Beserkly so he is considered to live in a warm climate. ( I think the bay area is cold, but thats me). Do all dual carb setups lack chokes?

My foot needs to be on the pedal a bit to get it to catch and run smooth, a few seconds. I suppose it may be different for folks in Tahoe and the midwest of course, but even there, you could use your foot as a choke, just keep the throttle open and feather it to keep it running. It does not take long at all for it to be warm enough to idle on it's own.

Thats what I am thinking. It also removes one more system that has the potential to fail at the worst of times.

No chokes on my 1904 with dual Kadrons- just keep my foot in it for about 2 minutes or so until she idles smoothly and oil pressure drops to reg. operating pressure.

Adjusted right a choke works Great , with no warm up time, you start and go. Its that
easy, people tend to set them to rich, thats where the problem is. They work very good
set up right. Just sayen. Smile

I've got the stock choke setup on my 34 PICT. I like it. When I go out in the morning, I tap the gas pedal once, turn the key and it starts and idles immediately. By the time I go in and make my lunch, it's warmed up and ready to go.

Properly set, chokes set the idle higher along with the closing the butterfly. As it warms, they open up and the idle falls. I worked hard to get a replacement for the broken choke on mine, glad I did.

I think that's part of the problem. It's not good for the cold engine to be turning at a higher rpm like that.

Greg, I agree with the high idle at start not being the best for your motor. Breck

Keep in mind, the Muir book is for the stock setup. I disagree with him to a point. I find the choke helps on cold days, but they retreat if you nudge the pedal after just a few seconds. That said, they really don't do anything you can't do with your foot if you're not fiddling with a cheezeburger, the kids, your phone, etc.
5 minute warm up in non-winter climate is excessive. One minute is sufficient to get the oil moving.
