Hey experts! I'm looking into replacing my stock carbs on my 2lt 76 bus "full rebuild 1yr ago" It seems everyone has an opinion on webber, empi etc... Is there anyone around that can educate me on this subject before i spend the $$ as Id like to do it once and do it right.

Thanks

There's quite a bit of discussion on carbs in previous threads if you have a stab at searching on here. Remember to change how far back it searches.

That being said, stocks are pretty nice if they are behaving. I went for a single weber progressive because it was affordable compared to fixing my stock dual solexes. That being said, Look at that option like this:

Stock duals > Single Weber prog > Broken duals.

Pretty much a 'better than nothing' alternative.

Can't really comment on other setups, but thought I'd just paint in my own little corner of the picture.

If at first you don't succeed. Build, build again.

the main item to repair of the stock 2L carbs is the throttle shaft bushings

this is the major item that failes and gives most problems sucking air

Vintage Vee Dub have these available in Sydney

I read it on FACEBOOK so it must be true

Hi

The stock carbs on a 1700 - 2000 Kombi are hard to setup correctly unless you know what your doing.

They have 3 idle circuits, left and right carby contribute to the idle mixture, the left carby has an extra idle circuit that feeds both sides at once, these idle circuits is where most tuners fall down as well getting the chokes to come off at the correct time.

The left hand carb with the central idle circuit also has an electric shutoff valve that often comes loose and flogs out the hole in the carby top, this can be fixed but it can be hard to find the person with correct tooling.

I have not used any alternative twin carbs on a Type 4 motor, but I imagine that a single in the middle would need to be jetted fairly rich to achieve smooth running and the economy would suffer.

If you have the money ($1k-$1.5k) go twin dual throat - weber or dellorto - and get a good quality linkage. I have fiddled around with a single weber and dual single throat webers (ict 34) on the same bus as yours and was underwhelmed in both cases.
