David,
Thanks.
Currently my advance is set at ~20 degrees at 1000 rpm, and I'm not getting any
pinging at all even when driving up a hill in fourth. So what this tells me, is
that I should probably try advancing it further, until I begin to experience
pinging, and then back off slightly. I'm using the my orginal distributor, with
the only modification being the Ignitor electronic ignition, and I still need
to hook up the vacuum advance.
This gives me a good place to start from
