Right now I'm running a stock 1600 DP in my Baja Bug.  I want to upgrade the carb for a bit more power and response.  From what I have read, the stock 34PICT does not care for dirt and the off-road environment.  Reliability is also a key issue.  I would like to stay with a single carb.

 

I am debating between a Zenith 32 NDIX and a Weber 40MX.

 

If I build up the engine in the future, the largest I would go to is a 1776.

 

Anyone have experience with the Zenith?  I realize it may be considered "Old School" compared to the Weber but I'm hoping it may be easier to set up.

 

Are there others I should consider?

Old carbs like the Zenith can way more trouble than they're worth, especially since there isn't a huge supply of spare parts left.

I'd stick with the Weber for ease.  However I'd highly recommend against a single carb setup.  Drivability and fuel economy will both suffer.

As for dirt, well no carb likes to get dirt in it.  Use good aircleaner assemblies (not stamped steel) with good air filters and pre-filter (foam wraps) and keep them properly oiled and you should be ok.  Make sure to use a good fuel filter too.  --Ryan

This prompts another question:

 

In a conversation about carbs I asked about dual 34 PICT-3s. There is some sort of dual Solex carb on the market, so why not the Old Reliable? I thought the sneers wouldn't stop, but in the conversation about them a fellow mentioned that motorcycle carbs have advanced carb technology quite a bit in recent years. He then recommended dual motorcycle carbs made for 1500-1700 cc engines and swore that they would be more efficient and cleaner than carbs made for cars, since those haven't had any research put into them for a long time. 

 

I can't say. What do you think?

Tough to beat a set of Webers or Dells, those carbs are so incredibly 'tuneable'.  I mean they were/are a carburator that was never developed for one specific use, they were intended to be versatile enough to work on any setup, and if you know what you're doing, they will. 

As for dual stock solexs I wouldn't waste my time.  You'd have to fab everything yourself and they are as easy to tune as more traditional carbs.  --Ryan

not to highjack this tread, but i have similar questions. so in other words, a weber progressive or single 40IDF really isnt worth the money? i had a progressive on my 71' baja and liked it. but it could have used more power. i guess i could go with dual 40 idf's but thats expensive. I dont have a vdub right now, but im in the market for one. I just sold my corrado G60 and i want my baja back. can i put dual idf's on a stoc cam 1600 and have it work?? i woud think it'd be over-carbed myself, but im not expert.

I like my progressive too, but it was a night and day difference when I went to dual 44s.  Properly tuned a set of dual Webers will run nicely on a stock engine.  --Ryan
