Hi,
Thought I'd put the results of my experiment on record. I've got a '74 Std. Beetle that came with a 34 PICT and 009, and my roomie has a '76 Van with 2.0L stock FI. We're in the process of swapping the type IV engine into the Bug and the 1600 into the van, but in the mean time I'm driving the bug, so I figured I'd try the SVDA distributor from the van on the 1600 engine. The bug runs pretty well but the stumble was holding it back.
The dist from the van is VW code 0231 168 005, or Bosch code 021 905
205P. No doubt the advance curve is not ideal for the smaller engine, but the engine still runs noticably better. The stumble is not completely eliminated, either it could use a bit more advance or the lack of manifold heat is showing up. Still, it makes a big difference to drive and is noticably peppier around town.Experiment, success.
Now a question: I've read about soldering up a hole in the throttle butterfly of the 34 PICT to improve its responsiveness with the 009. I've also read this is a good thing to do even with a better distributor. Is this for real? We want the 1600 to run as well as it can with out spending a bunch of money on it.
Peace, Harry
