distributor cap, where the wire's connected, you'll see that there's a
second connection tab there, labelled on the side of the cap as "Tach".
Guess what...

Good one Ken, I got the message no problem. The cap was pretty dusty and after I cleaned it off I could see the words.
I'd like to ask more about how to actually connect here and if I decide to install a tach in the dash, is this where I would tap into?
Anyway, before getting the answer about the tach take-off on the distributor cap, I'd borrowed a digital tach and stuck a reflector on the harmonic balancer.
After she warmed up, my idle averaged about 720-740 in park so we tried bringing it down with the throttle screw adjuster ..... without success.
The screw backed off but the throttle cable/linkage didn't follow so I pushed the throttle closed and got her down to 640-660. Exercising the linkage back and forth the stop was more and more prone to sit at the screw setting and finally gave the whole linkage/shaft/cable etc a good drink of silicone lubricant which seemed to do the trick.
Putting her in drive, she idles at the high 500's with no sign of stalling or choking so maybe that's ok? Haven't been down any steep grades since, but I'll report back after I do the next run.
