VW 105-1 30 Pict-1 Carburetor – The Choke Processes, Part I

By the time Volkswagens were “in the womb”, carburetion was not a new thing. But the German Engineers tasked with creating a viable engine system for Ferdinand Porsche had to create a system that would work with the air-cooled engines which were being demanded. Bit by bit, the VW carburetors were evolving into what would become a virtually fool-proof unit.

With the advent of the 12 Volt Electrical System, Volkswagen was coming of age. Carburetion would be just one of the areas which would benefit—with better starting possibilities. Let’s look at the Choke Mechanism on the VW 105-1 30 Pict-1 Carburetor.

While there are several parts to the Choke Mechanism, it is relatively simple.

But first—what is meant by “choking the engine”? “Choking” might better be termed “restricting”—because that’s what’s happening. When the Engine is dead cold, the Fuel Mixture must be more “rich” in gasoline with less air. The Engine is “hungry”. So, by restricting (or choking) the in-coming air, this need can be met.

Eventually, in a matter of minutes, the Engine will be running well and will need more air in the Fuel Mixture as it begins to reach operational temperature. It will be “starving” for air. Now the restriction on air can be relaxed—the “choke-hold” can be relaxed and the Carburetor can seek its own Fuel Mixture levels as needed.

We will be examining only the Upper Half of a Carburetor during this discussion of the “processes” or elements which comprise the Choking Mechanism.

1967 VW Beetle Community


I tell people all of the time that the Vintage Vehicle Hobby revolves around people. It’s more than just a hobby—it’s a Community! PEOPLE drive these Vintage Volkswagens.

When I attend a Volkswagen Show, I go for talking to people about as much as I go for seeing the cars. Really! For me, it is a non-stop talk-a-thon. I’m really worn out from talking, interacting and listening to all of those VW Community PEOPLE!

It was Neva’s and my pleasure this week (1/8/18) to have a visit from Ron Waller of Phoenix, AZ. Ron has visited us once before, about a year ago. He and his wife are in Texas with family but he took time to drive over to spend time with us, as well.

We had a blast! And, we didn’t nearly exhaust the subjects, including, of course, all things Volkswagen.

One of the major topics was Ron’s and Diane’s experience on the Border-to-Border Treffen Cruise down the West Coast of the USA, which they experienced not so long ago. And, what an experience! I read and re-read Ron’s account of the trip—but to hear it in person was something else!

“I really want to do this Cruise”—that theme kept going through my mind. Ron and Diane were the only ones to drive the entire route in a Beetle, their 1967 Lotus White Bug.

I listened as Ron recounted their preparations. They worked with a local VW Specialist in the Phoenix area. They checked and re-checked the car. They made up lists of supplies. When the time came, they were ready! And, then some.

I watched Ron’s face as he traced the route in his words. Some difficult times, some really great times, some frustrating times, some times when they wanted to do a victory lap! If you have driven a Vintage Volkswagen much, you know the feelings herein described.

We had a grand time visiting but, all too soon, Ron had to get back to family.

Don Hoopers’s vintage VW Uni-vents

From time to time, we’re lucky enough that our awesome readers randomly share gems such as these with 1967beetle.com. Very nice. I mean, NICER! Thanks to Don Hooper for sending this interesting piece of vintage VW history our way.

Now that I have spread the word amongst the 1967 Beetle community about my 40 year affair with my 67 Beetle Type 151 Cabriolet, I thought maybe some would enjoy looking at some parts I bought years ago.  I wonder how many here were aware that an in-cabin fresh air ventilation system was available for their 1967 Beetle? Well, it was available as an aftermarket, owner or dealer installed accessory know as the Uni-Vent Air Ventilation System.   Produced by Uni-Vent Co. Inc. of Jacksonville FL and sold by authorized VW dealers, the kit included a plastic tubular vent pipe system with scoops for each horn grill, that routed up inside the inner fenders to 2” holes punched into the kick panels on sedans and Karmann Ghias.  Two round vents units with spring loaded rotating caps closed the system or allowed for air to be directed up, down or sideways in the foot wheels.  The assembly was not made to fit the unique convertible kick panel shape.

I bought my NOS set from Bob Scott at Vintage Parts in Glendale, CA in January 1985 for $80 plus tax, intending to install it in my daily driver 1967 Lotus White sedan.

My plan was to make my daily 40 mile drive on Los Angeles Freeways through hot summer months more tolerable.    I know from the literature included that the set was extremely effective and would have made a big difference in my drives, but I never got around to doing the installation before I sold the car.   Hence the set has sat on a shelf in my garage for the last 32 years.  I thought it might be enjoyable for others who actually drove their 1967 beetles daily to travel back in time through this story and these pictures and remember sweltering days puttering along in the slow lane in the San Fernando Valley or elsewhere in obsessive heat. What a joy those days were!
