 Posted: Mon Mar 20, 2017 12:26 pm Post subject: 1964 Notchback Timing Question |
 |
|
Hey Guys,
I am doing something wrong. I am timing my dual solex notchback with distributor number ZV/JCU4R3. I get the engine up to 3000 RPM and go with 28 degrees and then let it fall to idle and its happy. When I go for a drive and get up to freeway speeds, I lose power and I get some hesitation.
I would love some advice. How should I correctly time this machine? The bentley is not really clear so I need some tribal knowledge. Thanks in advance (no pun intended).

Distributor: VW 341-905-205, Bosch ZV/JCU 4R3 (0231 150 001)
Replacement: VW 311-905-205R, Bosch 0231 150 010
Points: 01 002
Condensor: 02 006
Rotor: 04 006
Cap: 03 002 (NLA)
Coil: 00 001 (Blue Coil 00 016)
Vacuum Can: 1237 121 179 (NLA)
Ignition Wires: 09 003
Spark Plug: W8AC
Timing Set At:: Static Timing: If Pulley has two notches, it is set at the right notch which is 10 Degrees Before Top Dead Center (BTDC). If the pulley has three notches, it is set at the right notch which is 12.5 Degrees BTDC.
(Note: Models timed at 12.5 BTDC usually required high octane gasoline)
Advance/Retard Range: Vacuum: 8-11 deg Adv (approximate). Centrifigual: 15-21deg @ 4200rpm
Distributor notes: This was a unique distributor installed on the "S" Models in 1964. At first glance it looks like a Beetle 36hp "cast-iron" distributor with a push-on (not screw-on) vacuum advance unit (and it does use the 36hp points). In addition the centrifigual advance was a dual weight model, while most other VW models using centrifigual advance used single weights. Dual weights do allow for better power through all acceleration modes and it's a shame VW didn't continue it. Having owned a 64 Notchback 1500S, I was impressed at the response of this distributor throughout the powerband even when I upgraded to a fresh 1600 engine. Even though used only one year and some parts like the cap and vacuum can are hard to find, I whole heartily recommend this distributor for any carburetted Type 3 application, whether for sport or every day driving use.

Thanks for the info W1K1. Much appreciated. So my notchback is a 1964 S model and it has 3 notches on the pully so I will set it at the 12.5 when cold. This one year distributor uses vacuum and centrifugal advance.

This table is in Swedish, but you can look at the illustration of the timing notches.

Keep in mind that with this distributor, you have to pull 2 plug wires off to set the timing and idle speed. This is because the advance is already coming in at the 700 rpm engine speed.
Contact Pedro or Jason for specifics.

Ok got your PM. Static timing is just that. Set the fan notches to their required position then take the dizzy to the point where the points touch - boom static timed. No taking plugs off. No special cants and what not. Pedro will get way more involved than that nut thats static timing. Optimal running is beyond that and will include you tweaking said dizzy to its optimal setting. All mechanical devices require fine tuning.
