Making the Weber Progressive (32/36 DFEV) Work on the Aircooled VW Engine

DFEV Intake Preheat

Here at ACN we have gotten enough tech questions asking about the Weber Progressive Carburetor that we felt it was time to get a good article up on the subject. These are our OPINIONS on this subject. Hopefully this article will help some folks, who really have no idea what they are doing, to get their progressive running well.

If you have an EMPI progressive, understand that is a Chinese copy of a Weber DFAV/DFEV. We suggest that you get a real Weber DFAV/DFEV.

The DFAV and DFEV are the same basic carburetors, BUT the “A” stands for “Aqua”, or water. Put simply, the “A” is just a water choke version, and the “E” is the electric choke version. Because our cars are aircooled, we never ever deal with the DFAV. But if you pull one off of a Pinto or another car in the junkyard, you may

Rebuilding Weber 48 IDA VW Carburetors

How to Rebuild Weber 48 IDA VW Carburetors

The Weber 48 IDA has been used for decades by VW enthusiasts whose goal it is to squeeze every ounce of performance out of their engine. Problem is, production of these coveted Webers was halted many years ago. These excellent VW carburetors in decent condition have become rather scarce! Typically VW performance engine fanatics have to resort to scrounging the swap meets to find a pair of 48’s and even then, they may not be lucky enough to find a pair but have to acquire them one at a time. But if you are lucky enough to acquire a set in usable condition, and you are willing put the time, money and energy into rebuilding and tuning them, you WILL be rewarded. The Weber IDA’s sheer size will likely result in gasps of awe and astonishment from those that have never seen them before!

VW Carburetors 101: Carb Selection Options

VW Carburetor Options - VW Technical Article

Aircooled Volkswagen enthusiasts have quite a few carburetor options. Performance increases that can be gained by going with aftermarket carburetion are a common consideration, but without a little guidance, you can end up with nightmares associated with poor carburetor selection or poor tuning.

VW Carburetors 102: VW Carburetor Jetting

VW Tech Article - Basic Jetting Theory and Procedure

After springing for a set of carburetors, some people bolt them on, and are “pleased” with the results. Others are upset by a backfiring, or smoke belching monster. In either case, spending the time to properly jet a set of dual (or single) carburetors is a worthwhile task, since receiving “perfect out-of-the-box” carburetors is one of the biggest myths in the VW industry!

Proper jetting varies depending on engine size, elevation, cam overlap, etc. Jetting is so specific to an individual engine that two identical engine combos with the SAME carbs can even require different jets! The moral of the story is: With your engine combo, carb information and driving elevation, we can advise and get you CLOSE, but to know that your carbs are jetted optimally, you will need to spend the time necessary to dial it in. It IS worth doing for drivability, engine life, and

VW Carburetors 103: How to Synchronize Dual Carburetors

VW Tech Article - How to Synchronize Dual VW Carburetors

This article contains the step by step, detailed procedure for synchronizing dual carburetors on an aircooled VW engine. But before you actually tackle the syncronization, remove the air cleaners, and make sure there are no vacuum leaks (spray starting fluid around the carburetor bases and intake manifolds while the engine is idling). Make sure the engine’s ignition timing, valve adjustments, and other items are all correct also. You do this to ensure that you are adjusting the carburetors to a TUNED engine, not one that has problems.
