Been many years since I put in a Pertronix, but I seem to recall adding an 
'extra' loop on the inductive pickup.

Hi Bob, 

I ran into this when I first installed my Pertronix on my positive ground BJ8. 
I found that the Pertronix doesn't draw as much current as points and 
therefore does not create enough of a magnetic field with only one loop on the 
back of the tach. I ended up splicing in some thin wire so I could make 3 or 
4 loops where there would normally only be one and that made the tach very 
responsive and accurate. 

You might try this. 

Cheers, 
Chris
