[ochre1971]

I have what I believe to be HEI in my 71, see picture to confirm. I really know very little about these except for the basic function.

While on a moderate road trip over the 4th she failed to start one morning. Cranked over just fine, but sounded like she wasn't getting any fire. I removed the air cleaner and started wiggling wires around at the HEI connection while my wife was cranking, to see if I had just lost contact somewhere. She fired right up at that point.

So, my question is, is there any maintenance I should consider doing to this thing? Are there common problems I should look out for? Anything from the crowd with more knowledge than me, which is an admittedly low bar, that I should be aware of?

Thanks for any input and education.
