Carbs

Those are 40mm Kadron carburetors.

What Ted said....

Cabron carburators...

Those pictures were of the carb on the Rt (passenger side)

 

These are of the left and say Solex on the screw and the round cover, odd.

 

 

That is also a Kadron carburetor. 

"Kadron" is a kind of shorthand for a specific type of Solex carburetor manufactured under license by Brosol and sold by the Kadron company of Brazil. I'm not sure the Kadron name is actually embossed anywhere on them but they have a distinct appearance.   

 

So you're right that they're Solex carburetors, it's just that there is a huge variety of Solex carburetors that were manufactured for probably most of the European and Japanese auto industry at one time or another.  The term "Kadrons", on the other hand, refers only to the specific type of Solex carburetors that are in those pictures.

Ted pretty well covered it. I will add that the Kadron VW dual carb kit has been around since at least the early '70's (I saw my first set in '74 and bought a set a year later). They are a decent carburetor set up, simple to install and tune, and a part of a lot of people's introduction to VW high performance. If buying a set (especially used), one should figure getting the throttle shafts machined for bushings, as even new carbs can leak. Jeff at Kaddie Shack (advertises on the Samba) provides this service and seems to have a good turn around time and good customer service. Low Bugget (AJ Simms) also specializes in kadrons (including modifying them for much larger motors), but has a reputation for horrible customer service, as evidenced by the Samba thread in the Samba Feedback Forum. They are fairly versatile and work well on stock 1500's (with single port manifolds) as well as larger motors up to about 2 liters, the caveat being the 28mm venturis they come with may restrict power on a larger motor if too much duration and headwork is used. There are larger venturis available and even larger throttle bodies and high-flow air cleaner mounts (which all work), but at this point it may be better to spend your money on some Webers or Dellortos, as a new set modified to run on a larger than 2 liter that goes to 6 or 7000rpm costs over $700.    

the carbs will work great for motors up to 2 litre, they make lots of torque, which is good for the street. they will run out of steam about 4500 rpm. so it depends on how you want the motor to run. bill

Thanks guys. So I have a bit of hesitation on throttle tip in and then pulls strong. Based on what I have read and seen it seems that balancing with a snail gauge will possibly cure. Does that sound correct? Any other advice?

The accelerator pumps could be not coming on enough; iIrc the nuts should be turned in 1/2 or 3/4 along the rods. 

dont know what a snail gauge is?i use a air flow meter. the acc pumps should be checked with a small vile to measure the squirt volume. also the acc pump nozzle should be pointed directly at the throttle plate and the body, so time it hits their its drawn in. if its off it causes a stumble. bill

This is it also known as SK Gauge. Needs an adapter for Kadrons I believe.

 

you will get better performance&mpg with a set of idf/hpmx 40's or if over 2100 cc's 44mm crabs if you like more topend charge.

Adapter = small frozen juice can....yup it does suffice ~
