Is it possibly a bad condensor? My friend's 1600 would backfire and miss for
no reason, and it started doing it suddenly. It was a bitch to start but
eventually after it got warm enough it would run but very rough. After we let
it cool down for just a bit, we refired it... it ran ok for a short period of
time, then began the same behavior. My brain said "Something is getting hot
and sucking spark away." So we changed out the condensor... problem
immediately solved. BTW, he had messed with the point gap exactly as you have
described and was able to get the car to run at certain RPMs, but it was the
condensor the whole time. This may explain the inability to change dwell as
well (?). Cheap and easy to find out!

Could be the rubbing block is worn out and you need new points.

Still adjusting the car after the long road trip and I'm starting to wonder
what's up with my points. So here's the problem -- above 4500 rpm's, under
any load, I'm getting the chinese fireworks out of the back of the tailpipe.
My thought: maybe I don't have enough dwell; not enough dwell => not enough
magnetic field => weak spark. Right? So I go to check my dwell and it's a
sorry 37 degrees. My attempts to bring it up to the 49-50 in spec. are
rewarded with a car that doesn't start at all.
Who says this means that my points are shot; or, more specifically, that my
foot is so shot that the geometry can't both give me enough dwell, and
enough separation for a really nice spark.
I know this means that I should be going away from points and condensers and
buy an electric system, but I'm a poor, out of work, attorney with student
loans and an expensive dry cleaning bill who can't afford the upgrade just
yet.
