Tip for any interested- Go down to the hardware store and dig though the metric hardware for some long M5 machine screws. Grab an old pushrod, and cut some spacers- these ones are about 50~60mm long. Exact length depends on the machine screws you can find- I think these were 75mm long. Easy low-buck high-flow mod to lift the brace out of the throat of the carb! All you do after that is trim the center stud to match the increased height. Not pictures, but I also cut a spacer for the stud so that the air filter lid has something to tighten up against so that the lid doesn't warp when you tighten the nut or wingnut down.

This picture was taken about a month after I started my battle with Kadrons, and about 5 minutes before I decided to go with something else. Still, I love the look and the performance was pretty good, but spark plug, exhaust and A/F readings coupled with dripping throttle shafts on new carbs killed the relationship. Who knows--I might come back to them in the future.

Secret tip-

The VJU4BR8 (0 231 115 040 is the alternate/later model number) is identical mechanically to the "019" with an added vacuum advance can. It is adjustable for both total advance, as well as sensitivity. It is a killer way to go with kadrons, and is a period correct part.

In fact even if the hose for the vacuum advance is unplugged the vju4br8 will work according. It's mechanical advance curve is sufficient. Cool looking engine. But I would route the breather hose at the back of the fan shroud to free the engine bay from too crowded. IMO.

Here's an update, showing them hooked up with a tee connector on my (what I now know is) 1776.



They run very nice and give great (28~) gas mileage now.

I ended up cutting off the bottom of an old tube to give it more room. Any ideas on the small ball?


I'm pretty sure you can get them from kaddy shack

Loving this thread guys. I'm keen to get some Kadrons again, had a used set back in the 90's and as far as I remember they were great...and that was with an 009! Imagine it's better now we can modify to run with an svda.

Looking at the hard fuel lines, it seems they were never intended to be used with a regulator, but now the advice is to use one, perhaps they were better made back in the day?

How do you guys find them in winter, I have a daily driver so it is a consideration, but I've come to like them again so much, all practicalities are going out of the window! Wink

Here's my set, the breather tube has been cut and welded in the aircleaner, and hole drilled underneath for whatever reason. I have the perforated steel covers for the filters, but they are mangled, and in the garage somewhere. I've got a set of hardliners made from brakeline I fitted to them. They sit on a set of steel manifolds.

Here's how I modified them for SVDA...

Get yourself a 3/16" drill bit, and drill out the port plug on the carb body, I did this while my carbs were apart and venturies removed, but you are only going into the plug about 1/4" before it spins out with the bit. Next, get some 5/32" tubing and cut and deburr it. I found for my carbs that 7/8" worked great. Tap it in.

Here they are installed on a 1600DP. Haven't tested the vacuum pull yet, since I need to grab an SVDA first.

The manifolds will fit any 1500cc or 1600cc single port engine. IF your 67 still has the original motor.

Thanks for the clarifications, conrad. After looking at the brake junction photo, and then the one for the fuel lines, the fuel lines are definitely of a (slightly) larger diameter. Therefore the union nuts are also larger.
