I'm also using the pertronix as a trigger for an MSD. I got them to work
reasonably well without the MSD but there was always some instability. The
MSD solved that. I have my doubts that multispark does anything, but who
knows.

Nock,
As Arte Johnson Would Say: "Veeeeery Interesting!
I used a Pertronics as a trigger for an MSD when I had a Triumph engine in
my black car (Tiny Tim). It did not display any of the oddities that you
describe up to 7500 rpm (where I had the rev limiter set). So I am
wondering if the multiple spark is solving the anomaly or perhaps I just got
a good one.

OK, I've gotta leave the "lurk" mode to wade in on this one...
I wanted to use a Pertronix in the worst way on The Duke of Oil, and I did.
In the shop it seemed good. No problems without a load on it. First session
out it had a high speed miss! I yanked the dist and put a points unit back
in, no more problems. On the dyno I tried again and it just wouldn't pull
past 5000. Again popped in a modded Lucas unit and saw no ignition based
problems.
Being a very slow learner (or is that stubborn) I spent some time with the
unit on the bench. The first thing I found was that the Petronix unit was
not correctly phased using the supplied installation parts.
After hacking and hewing a different mount, the phasing problem was solved
and it showed a nice spark under any load I could put on it while on the
bench. This seemed to alleviate much of the problem. Once again the Petronix
dist was installed in The Duke. Once again it failed to perform at high
RPM's. Now I really was getting my dander up about this.
There must be some way to make this little bugger work! I sprang for another
new unit as there MUST be something wrong with the unit I had.
After installing the new unit into the Duke I again found it "lacking"
at high RPM's.
At this point, The Duke is back to period correct Lucas and points...anybody
wanna buy a coupla slightly used Petronix units?
Always gettin to the point(s)
