Just in the last couple of days I have experienced the "pause that makes your heart skip". Under mild acceleration only occasionally the engine pauses for just a fraction of second and you think out of gas? bad coil? I've only noticed it under easy acceleration and while turning, no evidence while hard acceleration like freeway on ramp. I checked the distributor wire from battery and is hard as a rock and insulation was cracked in one spot so I wrapped with electrical tape but.... today it did it again pulling away from curb, just a quick fractional second lack of power like someone turned off key and back on as fast as you can.

Now this makes me start thinking... just recently I checked plugs and were light tan, no carbon or buildup, just what you want but I changed rotor as it was arced up a bit, I was going to change the cap also but couldn't find it, could of sworn I had a spare in my spare parts bin. Guess I'll find it when I look for something else! Besides changing the rotor I cleaned the buildup on the advance weights, springs and rest of distributor base and relubed sparingly with white lithium grease and silicon spray lube. Anyway, since I changed the rotor the tone of the exhaust seems a bit different kind of rich like the sound of stuck choke, popped off the air cleaner cover and choke wide open so it not that... now I'm wondering if I'm imagining it all! Having changed the rotor I can't imagine that the timing changed and did not use too much grease.

The good side of this story is that I think I have better acceleration and power. Cleaning and relubing the distributor and weights helps and sucking on the vac tube it seems the advance reacts better. I hope this is not just a placebo effect, but what about the "pause that makes your heart skip"?
Any ideas?

Thanks for pondering,
