Weber Carburetor Setup

This blog post discusses how you can setup a new Weber 32/36 DGV carburetor for your Ford powered Formula Ford. With these old Kent powered formula ford race cars, proper carbonation is key to good performance. My race car came with a old and tired carburetor. The throttle shaft had a lot of play in it, and it was fully prepped for road racing and not really suited for the time trials (Autocross) style of events that I run. The impetus for building a new carburetor was after discovering that the old carburetor was not delivering the right fuel amounts to the engine which was killing the power to the engine.

The Formula ford Kent engines are powered with a Weber 32/36 DGV carburetor. This carburetor has been used on a lot of different cars, and it’s a very popular choice when restoring older vehicles where the original carburetor might be harder to find or fix. The Weber 32/36 DGV is a progressive two barrel carburetor with a manual choke. There are other variations with different options, but the 32/36 DGV is the most basic model available in this series of carburetors. This blog article discusses how you prepare this carburetor for use on your Formula Ford so that you comply with the rules.

Here is the basic carburetor as it was delivered.

The basic preparation is pretty easy. We need to remove the choke assembly and plug a few holes that we won’t be using anymore. Removing the choke is really easy, the hardest part is getting the choke shaft removed. To remove the choke shaft, remove the screws holding the choke plates, and the choke plates will slide out of the choke shaft. Then remove the c-clip connecting the choke rod to the choke shaft. Once everything is clear, the choke shaft will slide out of the cover assembly

The rest of the choke assembly is straight forward. Once you are done you have most of the hard stuff done, now we need to plug a couple of holesplugging holes

I used some JB-Weld to fill the holes, you will want something that is fuel and heat safe to plugs these up. For the choke shaft, I used some blue painters tape to plug one side of the hole to create the plugs

the last step will be to adapt the throttle linkage to your application. Each car can be different here, so your best bet will be to use the setup from your old carburetor. You can find parts from Pegasus motorsports. I had bought their throttle control lever, but it would have needed a few “adjustments” to make it work on my old throttle linkage. the original piece was the same design, so I just reused it.


There it is, all nice and shiny! The next step will be to tune the carb, and I’ll leave that for another post.
