FOT,
I have a TR4A with the mild level of preparation (D Cam and other
modifications pretty much per Kastner's book) . I recently installed a
Pertronix points replacement system.
Before the replacement I could easily pull 5600+ rpm. Now it breaks up at
about 4800 rpm. Nothing else was changed. Any ideas as to what the problem
might be? I have noticed a definite improvement in idle smoothness but that's
all.
Could the plug gap be the problem? I see on Pertronix's web site a note about
increasing the gap by .005. I haven't tried that yet.
