SVDA 034 Distributor

with 3BOS4U1 Electronic Ignition

for 4-cylinder Air-cooled VW & Porsche

The Hot-Spark SVDA 034 Distributor with Electronic Ignition

The perfect replacement for most air-cooled VWs & Porsches

Brand new vacuum-advance SVDA 034 Distributor for Volkswagen Beetle, Ghia, Thing, Bus, Type I, II, III, IV, Porsche.

Includes 3BOS4U1 electronic ignition conversion kit already installed, ready to run in your air-cooled VW or Porsche – Just install distributor, connect the red wire to the coil's positive (+ or 15) terminal and the black wire to the coil's negative terminal (– or 1), connect vacuum hose to carburetor/throttle body and set the timing - Simple!

Zero-maintenance 3BOS4U1 electronic ignition means you won't have to fool with points and timing again – always stays in perfect tune!

Our SVDA distributor is a quality reproduction of the original, vacuum-advance Bosch 0 231 170 034 / VW 043-905-205, federal model distributor that came stock from the factory on the 1974 VW Beetle with 1600 engine and manual transmission. Perfect for use with the 34PICT carburetor. This distributor requires a vacuum source from the carburetor or throttle body (when used with fuel injection). Can use stock Bosch distributor cap, rotor, etc. Includes OEM distributor shaft O-Ring.

Some of the advantages of the SVDA 034 distributor over the 009 distributor:

• Better acceleration - helps eliminate the 009's infamous "flat spot" on take-off

• Cooler engine temps

• More power, throughout the advance curve

• Better fuel economy

• No need to run a rich fuel/air mixture to compensate for the 009's poor acceleration, which results in unburned hydrocarbons in the exhaust and reduced engine life

• Includes OEM distributor shaft O-Ring.

The Hot Spark SVDA distributor is ideal for use with most 12-volt, stock, air-cooled Volkswagens, except later models with factory electronic ignition and those with certain early Bosch fuel injection systems triggered by special contacts in the bottom of the distributor (Bosch D-Jetronic).

We assemble each distributor; everything is checked, adjusted and lubricated before shipping. We then set and test each distributor's advance curve for maximum acceleration and fuel economy, using a precision distributor testing machine.

The Hot-Spark SVDA 034 distributor fits the following Volkswagen models (12 volt, negative ground only):

• Type I - Beetle, Bug 1946-1979

• Karmann Ghia, 1956-1974

• Thing, Type 181, 1973-1975

• Type II: 1950-1979 Bus, Transporter, Station Wagon, Kombi, Westfalia Camper (except 1979 California bus)

• Type III - 1962-1973

• Type IV (412) 1974

• Vanagon 1980-83½, 2.0 liter, air-cooled (except California model)

• Most 4-cylinder, air-cooled Porsche with points distributors (except for for early 1970s Bosch D-Jetronic fuel injection)

• Models with Bosch L-Jetronic fuel injection: 1975-79 Bus, 1980-83 Vanagon (except 1979-83 California models)

Can use these standard Bosch replacement parts (same parts as Bosch 009 distributor):

• Rotor: 04 033
• Distributor Cap: 03 010

Timing the SVDA 034 Distributor

Use a stroboscopic timing light. Timing should be set initially at 30-32° BTDC at 3,500+ RPM, vacuum hose disconnected and plugged. Maximum advance, at 3,500+ RPM, vacuum hose connected, with no load on engine (car sitting still), light throttle, should not exceed 42-44° BTDC.

For proper operation of the distributor's vacuum advance, the vacuum source needs to be able to generate a minimum of about 8 inches (200 mm) of Hg. If your engine is running a high-lift, long duration cam, with cam overlap or an aftermarket carburetor setup without an available vacuum source, the vacuum-advance mechanism may not advance fully.  However, the distributor's centrifugal-advance mechanism will provide the same advance curve as a properly set-up 009 centrifugal-advance distributor, simply by capping off the vacuum port.

Compatible Carburetors: The following carburetors should produce the proper amount of vacuum for use with the SVDA 034 distributor (if they are fitted with a vacuum port):

• Weber  ICT, DFAV or DFEV
• Solex 30PICT-3
• Bocar 30/31
• Single or dual IDF
• DRLA
• Solex 30/31
• 1972-1974 VW bus with dual carburetors
• Kadron
• Solex 34PICT series
• Bocar 34PICT series
• 1975-83 Bosch L-Jetronic fuel injection ('75-'83 VW Bus, Vanagon, etc.)

The Solex 30PICT-1 and 30PICT-2 carburetors may not produce enough vacuum to take full advantage of the SVDA 034 distributor's vacuum advance, but the Solex 30/31 is fine.

If your car has Kadron or ICT carbs, connect the vacuum hose to at least one carburetor. If your car has dual IDF or DRLA carbs, run a vacuum hose to both carburetors, T them together and then run the vacuum hose to the SVDA 034's vacuum port.

If your 1971 VW Bus or 1971-74 VW Beetle/Ghia/Thing has the original dual-vacuum distributor and you replace it with the SVDA 034, you'll need to plug (cap off) the carburetor's retard vacuum port, which is the port located closest to you as you're looking at the carburetor from the rear of the car. Use the advance vacuum port, located on the left side of the 34PICT carburetor.

Works with Bosch L-Jetronic Fuel Injection: 1975-1979 VW Bus and 1980-1983½ air-cooled VW Vanagon (except 1979-1983 California models)

This distributor requires a 12-volt, negative ground electrical system.

Coil: Stock Bosch 3+ Ohm coil or HS34HEC high-energy coil required. Coil must have 3.0 Ohms or more primary resistance.

To measure primary resistance: Label and remove all wires to coil ( + or - ). Using a common digital multimeter in the 200 Ω mode, cross the red and black leads of the Ohmmeter. Allow 10 seconds or so for the reading to settle and write down the reading. Still in the 200 Ohm mode, measure between coil’s + and - terminals. Allow a few seconds for the reading to settle, until it stabilizes. Subtract the previous reading, taken with the leads crossed, to compensate for Ohmmeter's inherent resistance. Do not use a low-resistance coil, such as the MSD or Accel coil; they don’t have enough primary resistance for this application.

Measuring Coil Resistance (and more): www.Hot-Spark.com/Coil.htm

Test the charging system's maximum voltage: If the charging system voltage, measured at the coil's positive terminal, is more than 14.2 volts at 2,500+ RPM, the voltage regulator likely needs replacing. Too much voltage can damage the ignition module and other electronic components
