twin carbs

Is there any reason why one couldn't put a standard carb on each side in a twin setup ? would be loads cheaper that a proper twin setup !

Not as much power. And yes it can be and has been done, there are intake manifolds available for that even. Heck, even the factory did it on type

3's ;)

Thanks Jan

Is it more power than single ? I am thinking of bus low rev power, not bug high rev power.

My 78 bus has 'twin' carbs but I think it is set up a one carb split in two - one side does the idle the other does the main.

Yea I know your 78 bus carbs, I had a 78 too with carbs.. those carbs are almost useless :)

I recommend the Kadron kit. Easy to find jets for (air correction isn't replaceable but you can drill it out, thread it, and use main jets in it's place)

There is a ton of Kadron experience out there and good support from lowbugget.com

I tend to get the feeling that webers are a PITA to set up so if I was going to spend bucks I would go with kadron.

I did buy a carb from a 1.6 fiesta XR2 i ws going to have a play with. I have to get it mounted and see how it works.

I like to try and bend the rules - try and think from a different point of view, or am I just a cheap skate !

I have both set ups, the webers on the Puma and the kadrons on my bus. For the dollar amt, the kadrons are the best choice. I'm going to try a

2bl progressive holley on my bug when it goes together just to see how it works for me.

There was a holly carb called the 'bug spray' designed for a bug and very good performance. I dont know if they are still available. I have a 4bl holley on my firebird but holley isnt a make we get over here and thats the only one i've seen.

You can also try to put a set of dellorto's. You can try to find a alfa on a junkyard.

The progressives never seem to work quite right, and there are couple of fundamental reasons as to why.

IMHO, not worth the effort and cost.

I've had this on a shelf for years and I just have to try it. The carb was used on the chrysler "k" cars with the mitsubeshi engine option in the early years (1980 I think). I have an aluminum manifold for it from claudes buggies (CB) and remember some good reports of the time. We will see. Dennis

I remember a kit in the 70's (no comments) that used twin side draft SU carbs, on a single port. Dont know anything else about it, cept I had one...

\btw,,, Merry Christmas

IMHO, I think webers are easy. The tough thing are the crappy throttle linkages you have to literally redesign to get a pair of

44IDFs to open at the same exact rate. And damn are they sensitive to mis-alignment, too. That ain't the carbs fault, neither.

Jan, if you're refering to the weber 32/36DGEV, I know what you mean. I had one on a mostly stock 1600 and could never get the off idle bog to go away. It was not jetting. Top-end was excellent and so was idle. Anywhere just off idle to 1/3 pedal was all cafocked.

My best guess was that the redline manifold was the cause. A resonance at 1200 rpm or something about velocity.

I don't think it is the carb in that setup. If toyotas, fiats, and jeeps run fine with them...

It's the intake manifold. They are designed to run with very SHORT, HOT manifolds that have an open plenum right under the carb that allows for "turbulence" and even distribution of mixture.

It is almost impossible to make a manifold like that for a beetle, they certainly aren't available from any shop.

Jan, the manifold I have is cast aluminum with a large mix area and uses the exhaust heater tubes for heat. I will post pictures if you want to see it. Dennis

Ok Jan, I will get it out of the garage and take some pictures of the manifold and carb. Dennis

Aircooled.net has one that routes the exhaust not only through the base but in a loop up under the carb, best I've seen..
