All I did was clean the air filter on the carb. I dried it very well before placing back on.?????????????

Maybe it was really dirty and is now running lean?

Maybe bumped something or got something in a bind when working in there? Kind of thing I normally do! Even plug wire, etc.

I thought about that.... But, I have talked to alot of motor people. All say keep the points (can be fixed on the water).

Brad, if it's any incentive, I'm still (knock wood) running my original electronic ignition (OEM 1993) with no problems.

sure your plug wires and plugs are ok? these have usually been my problem when the engine starts breaking down at higher rpm's.

Sounds like Ignition secondary misfire, how old are the wires ? plugs ?
you can visually inspect them specially near the manifolds.
you can also get a spray bottle with water, hold the idle up to 1500rpm and spray the wires and ends down, -don't spray the dist- the water acts as a conductor and any bad plug wires will start to arc to ground [engine] it's a fast way to check for bad wires. of-course pull the plugs and have a look at them, or just replace them altogether

a ohm meter can be used and measure the wires one at a time end to end while bending and twisting looking for breaks and high resistance.
however mixed results can occur as there's no load on them.

since it was running fine before, I'd rule out flat cam, broken valve spring, burnt valve/s, or maybe you dropped something down the carb while the a/c was off ?

I vote that you got water in the ignition system too. Either in the cap, or in the wires.
