Hi Al,
I thought my #4 cylinder wasn't firing and the only way I determined
otherwise was to raise the revs and disconnect the other three spark leads one
by one
until it was running on the one suspicious cylinder.
Compression tests and comparison of the color of your spark plugs would be
next if you determine that they are all firing.
Another area that deserves checking is the distributor. It can cause revving
problems and rough running. Centrifugal weights can be sticky and rusty,
springs lose tension and the vaccuum advance sometimes freezes up. Worn
bearings
cause points scatter. That was the problem (among others) on our car.
