Meh, it's a crapshoot.  In Canada (eh!) only JH (and 2H) cars had CIS
K-lambda (i.e CIS with o2 and frequency valve)  That's 84+ Cab, 83+84 GTI,
84 GLI, and 84+ Scirocco.

I'm pretty sure that Ed's car originated south of the border, where K-lambda
was more prevalent in earlier models due to tighter emissions standards.


My advice would be to set the timing to stock, like Mr. Bubb suggests, and

Half a turn is a lot at idle, bog me out batman.

Cough cough... :)  For those of us without 2L ABA swaps, the WOT switch
should raise idle a little, not bog the engine... :)

Dude, grab your Bentley, a dwell meter and a cold one and run through it, if
your O2 is operational it's a 5 minute job... :)
