Ryan,
I have noticed that some timing lights just don't run 100% at idle on
some engines. It is not a positive indication of misfire. As an
experiment, temporarily reduce the plug gaps to .015" to .020" & see
what happens. If the ignition is weak this should help the situation &
make it run better. Just a clue, not a fix, unless the gaps are
presently too wide. .025" is standard.
A bad condenser can cause all kinds of strange problems. Easy to change.
