I took the the time this morning to go through all of my old receipts
and ascertained that my cam is indeed a .012, so will reset the
valves (currently at .016) when my back recovers.
Terry Sanders was kind enough to open his spacious and well equipped
garage and we tackled the performance problem.
First baffling piece of info came from putting timing light probe on
each sparkplug wire individually. . . . normal for 1 and 2,
intermittent for 3 and no light for 4. Pulled the wire off the plug
on 4 and there was excellent spark. Pulled the plug and observed good
spark. Reversed plugs 3 and 4 and 3 failed to light the timing light.
Replaced plugs 3 and 4 with used plugs from stock and got the same
findings. We cleaned the rotor and dizzy cap points and set the
timing, then test drove and got substantial improvement.
I resolved to replace rotor, cap, plugs, and wires.
Got new plugs on the way home (NTZ B6) and replaced them and then
took my favorite copilot and mother of my children for a test drive.
All was fine for the first ten miles or so, but then it started
acting up again. It would lose power (I think running on 3 cylinders)
for a few seconds and then kick back in. It stalled once but started
after a couple of clutch poppings. We stoppped for lunch and then
headed home on back roads, with a few of these incidents along the
way. Copilot commented that if one isn't really sure what you did to
fix a problem, you probably haven't fixed it.
I will take Skip's advice and go back from Pertronix to points and
will replace the components as planned. Do Pertronix units go bad?
