CIS-L mixture adjustment w/ dwell meter? (no Bentley w/ me)

[area53 at validpath.com (Jeff Toomasson)]

Hi folks - I've driving around my resto car w/ a ABA/RD motor a little now that 
weather's good. The head is P&P'd (though the jury is still out on the job 
quality) with a stock cam (for now) and CIS-L w/ knock sensor grafted in. It's 
running about as smooth as a VW engine I've ever had (which I hope it would 
since I rebuilt the block myself).

The trouble is that it just doesn't seem to have the 'oomph' that my 3A/JH P&P 
and G-grind does. That setup is running A2 fuel injection.

Now provided I have the timing setup properly (which I will check later today), 
can I run the dwell meter mixture test method on CIS-L? Or is that only for CIS-
E? I can't remember.  If so, is that method pretty straight-forward? Do I need 
any additional plugs or can I make a test harness?

On a side note, and probably related, I had to cut some of the idle adjuster 
screw housing off to allow for adjustment clearance. If this is a source of 
leaking vacuum would this be a contributing factor to the above issue even 
under load?

Thanks!  Jeff
