Timing a rebuilt 2.1 using digijet

[stegosaurus]

1983.5 2.1 rebuild on Digijet FI (not Digifant)

I am totally confused! The rebuilder is very adamant that the timing should be 35° at 3k. On the other hand, I have had knowledgeable Samba members tell me that it should be timed as if it were a 1.9. I also have seen a few threads here on the Samba but no conclusive answers. Is it the engine size that determines the timing or fuel injection system. Right now it's timed at 35° and it runs terrible!

Did you time it off the first or second mark?

And IIRC, the 2.1 and the 1.9 have different crank pulleys which means you need to time them to the engine, not the management.

35° at 3-3.5k rpm at top dead center. The actual RPM is whenever the mark is stabilized.

Doesn't matter which engine but you do need to make sure using the right mark on the pulley.

Follow information you've read from 10cent.

FWIW, I have a 1.9 Digijet rebuilt as a 2.2 and am running 5* ATDC @ idle and 40* BTDC at 3000 RPM.

I've had it like that for 60,000 miles with no problems and MPG in the low 20s.

If you don't have enough swing room to get where you want to be you may need to reposition the distributor.

I haven't re-positioned the one on the van but on other cars it was simply a matter of withdrawing the distributor and drive shaft then re-engaging the shaft off by one tooth (in the direction you need to go).

Wait for someone with specific WBX experience as it may be different or (I seem to recall) there may some precaution you have to take as you withdraw it.

Distributor is a NOS from Vanagain. The retard canister came with it.

/\ I'll give it a shot. Maybe it's the canister with vacuum hoses getting in the way?

The proper Digijet timing is 28° +/- 2° BTDC @ 3800+rpms with the hoses removed and plugged, just like for an aircooled with a dual advance distributor. Removing and turning the distributor drive is easy enough, everyone has a first time at doing this. You can use a dowel rod jammed down in to the center bore in the drive, a magnet, or a pair of duck billed snap ring pliers to raise the drive. A properly sized dowel rod 5/16"(?) will probably give the best feel. Slowly raise the drive turning it slightly as you raise it and keep testing to see if it has disengaged and will turn free. Once the drive turns rotate it about 30° and carefully let it drop down into place.

Make sure the dog on the bottom of the distributor shaft mates with the slot on the drive when reinstalling the distributor.

When doing this work DO NOT remove the plug wires from the cap, but just set the cap aside with the wires still attached. Removing the coil wire is fine.

If you have an advance style timing light you will be using the U shaped timing mark. If you do not have an advance style timing light you will need to make a new mark 1 9/16" to 1 5/8" to the right of the U shaped mark.
