Another Dual Carb thread ...

[TonyB]

I've been away from VW's for about 30 years ... but I'm wanting to complete things on my bucket list.

I've got a '62 ragtop that someone cut up for a Baja ... which is fine as that's just what I was wanting.

I've got a very sad '72 Super Beetle with what I believe to be a stock 1600 dual port (doesn't look like its been upgraded in any way) ... It runs and has about 115 pounds of compression per cylinder and I want to pull the engine to put in the ragtop (which doesn't have an engine anyway) but looks to have had the bell housing cut for the larger 12v flywheel.

I'm looking at a "Weber Carburetor Kit VW Bug & Type 1 Dual 40 IDF - tuned for VW air cooled Redline Kit w/ Genuine Spanish 40 IDF European Webers" (description straight from an ebay listing)
Over the years I've had 240Z with dual carbs (upgraded to a Weber 40DCOE 6pac) Several MG's with dual SU's and Strombergs ... so I'm not new to dual's ... but I'm not sure if these are the optimum for the Bug

Right now its just got the stock distributor and exhaust, but I'm thinking I'm going to upgrade both. For exhaust I want headers w/mufflers that aren't too obnoxious ... I have no idea what for a distributor, most likely something with electronic ignition.

Looking for better performance and still have good drive-ability

Am I on the right track?

Yes! Try to find out from the ad what size the venturies are. Most likely 28mm which is fine for stock heads. You might not need a different distributor from stock if those Webers have small vacuum tubes down at the carb base.

I've run 40 IDFs on near-stock 1600s that had just some cylinder head porting and a 1 3/8" header. Ran very well and smooth. This was at least 10 yrs ago, using a good quality centrifugal advance distributor because the carbs did not have the vacuum outlet tubes.

Does your '62 have a short engine lid to offer slight protection from rain to the carb air filters? If not, be careful that you park the car to avoid rain. If water enters the engine through the air filters and partly open intake valves, the water in the cylinder can ruin the cylinders over a long storage time. Otherwise you can fit a cover over the air filters for storage. Even a baggie will do, but remember to remove before next drive.

Thanks for the reply Rome!
In the description it didn't say what size the venturi's are but on another site that had more info it said they were indeed 28's

All this stuff is enough to make a return into the world of VW's pretty confusing ... I'm a virtual newbie all over again!

In looking at exhaust I ran across this, it says there is clearance for any dual carb setup, which is kinda what I'm wanting. I think. It doesn't need to be shiny, I guess that's just a bonus

I'm assuming (I know what they say about that), but the "mufflers" are kind of like the Thrush mufflers I put on my 65 MGB back when I was a kid and needed something NOW, but had to save up for a replacement from British Leyland. Not the quietest by any stretch of the imagination but I'm thinking it would tone it down a bit.

Again, this is just a knock-around car, drive to work on nice days ect ... I imagine it won't get driven any more than my 72 vette that its probably going to replace (because its so low, its really hard to get out of when you have bad knees!) ... the wife and I are still talking about that.

Always open to suggestions!

Those exhausts are terrible, performance and sound is shit. I went with a u bend offroad exhaust and added a 13in glasspack to it. It sounds great, not too loud not too quiet and fairly compact.

Vanillagurilla & Glenn, thanks for keeping me from making a huge mistake!

Vanillagurilla, my rear cage looks about the same as your's ... I'll look into that system ... did it come with that muffler flange on the end or did you have to add that? are they headers that you added the glass pack to?

This may be a simple question for some but I’m a beginner at this. I have a 71 super beetle I’m looking to fix up and learn on. It does run but it started to stutter in 2nd gear and then finally stalled out completely and wouldn’t start. Then I noticed gas spitting out when I press the throttle which I’m sure isn’t good. Of course I won’t attempt to start it up until I solve this issue. Is the carburetor shot or is it just an adjustment? The close up where it looks wet is where it’s spitting out from. Thanks.

I ordered a set of EMPI carbs, simuler to what I started looking at, and according to Gary at CIP1, are not only better but are less expensive ... I just hope I don't have too much carb for then engine I've got, but I want to use these on the next engine as well.

He also recommended this distributor with centrifical advance and electronic ignition and to put a rev limiting rotor on it, so I went with that, also instead of a more expensive Petronix (sp?) unit.

Finally I went with an EMPI header/muffler setup

Also got some little things like a Bosch blue coil, blue wires and new blue pushrods tubes as the seals were leaking on the old ones anyway.
Then some bling, aluminum valve covers and degree'd crank "power pully"

[mark tucker]

most of what cip sells is shit. knocks off's of knockoffs knock offs. good luck.

CB is good. I’m also a fan of John at aicooled.net. He’s very good responding to emails if you have questions.

Research the parts before you pull the trigger.
