Best distributor set up for modified CT engine.

[sarran1955]

Hello,

I am still working on my CT engine, fitted with conventional ignition and have decided to renew the dizzy.

The best part no in (VW) 043 905 205 ZB.... findeable but pricey, (for the californian 1974 super beetle)

Other options Serial Kombi 043 905 205 R.... cheaper.

What does the R mean.....reproduction

Helpful comments please!!

Hello,

I spent a useful part of yesterday evening sending enquiry e-mails regarding the best replacement distributor.

I do not want to use the VW setup, with its Hall effect sensor and amplifier. (pants smiley??)

The original dizzy had all this plus the pushme-pullyou vacuum bellows.

I have been running a stock T2 dizzy with appropriate coil.

I am getting a persistant misfire, sometimes to the point of running only on the left bank of cylinders.

Investigation shows a very tired dizzy shaft, with too much lateral play, (well it is nearly 40 years old).

0231170034 seems to be the best choice so far. the suffixes: P is for points. (also ZN I think in German), N is for the electronic version.

As I want to be able to use low octane essence, (currently running 95) in Eastern Europe it can be 87 octane, I originally looked at a points system.

However, I have found this:

A very good reply to my e-mail, and I am awaiting a reply to my latest questions.

I will keep you informed.

As I said.. fit the original electronic dizzy with a single vac advance module..
fit to engine time to 5-7.5 deg BTDC and forget........ enjoy big fat juicy sparks...... but then if you like tweaking and setting points every few thousand...

Hello,

The mysteries of the dizzy part number suffixes become clear.

I reproduce here a copy of the very helpful e-mail from Airhead parts.

Hi John -

The suffiz "ZB" is what Volkwagen of Mexico assigned the Bosch Mexico
produced 043-905-205, probably to differentiate between German (original)
production and Mexican (current) production. The biggest difference is that
the condensor side plug on the German production is square shaped (Bosch
1237330252, our # 02074) and the Mexican production is the earlier is round
shaped (Bosch 1237330220, our # 02054) through the side of the distributor
casing, so this should be noted when running this distributor and ordering
replacement maintenance parts. If ordering this distributor, be sure to
order the Distributor O-Ring, our # 111-905-261.

Best Ignition Coil to use is the original Bosch "Blue" Coil (Bosch
0221119027 [Spain] or 9224771008 [Brazil], we sell as the Bosch North
American # 00012). It is important that you avoid the Mexican produced Blue
Coil as it does not have the proper resistance to prevent Points and
Condensor burn-out. We only sell what Bosch is now producing in Brazil.

Outside of the fuel injection that was used in the North American market and
the smaller engine design, you cannot get better economy that the Solex
34PICT series carburetor used on European market Vanagons. To change to
anything else may result in poor mileage and power. The 34PICT-4 carburetor
has not been available new since the late 1980s, so the next viable
replacement is the 34PICT-3. Because I am sure the jetting is different for
the heavier Vanagon, it may be wise to swap the main jet, air correction jet
and idle pilot jet(s) from the 34PICT-4 to the replacement 34PICT-3 if and
when a replacement is done. The other main difference between the
carburetors is that the 34PICT-4 has a larger acceleration pump diaphragm
than the 34PICT-3, but should not be a detriment for the Vanagon
configuration.

We ship all over the world, so shipping any product to France should not
present a problem. We normally ship via Fedex into Europe.

VISA and Paypal is accepted. You can simply register on-line at
http://www.airheadparts.com in our shopping site with all of the appropriate
information requested and we should be able to process your order in a
timely fashion.

Thank You For Your Inquiry!

That seems to be pretty clear.

Below I post the link to their set up page, worth reading I feel, especially the trouble shooting,and hesitation article.

So I will look at the possibles, and make a decision this week end.

I'll let you know how I get on.

no no no - you will kill it!! CT engines are timed to 5 ATDC if using the original engine config/electrics - putting it that far out will make it pink into destruction in minutes.. CT's aways ran hot and are renowned for being good at killing off heads when setup as should be

I have found (by chance) that a DG water cooled dizzy will work on a CT but it makes it run slower overall as the advance curve is as you would expect all out - might be worth looking into seeing if a CU Aircooled dizzy works any better than the DG?.....
