That was very helpful for me just now, thank you!

This was a helpful thread. I have a brake shudder from the front right drum. Plenty of ideas here to work with. Thanks in advance! (For whatever its worth, I've noticed that there is a difference between drums that have been adjusted cold vs drums that have been adjusted after driving for a little while. Of course, this could be a symptom of something else entirely, but I wanted to note it).

Awesome post. Thank you. I think my 620 has a sticking choke as well. Interesting that the choke doesn't work like the anti-dieseling solenoid, but apparently acts like a stepper on the throttle plates. When I think choke, I think open fuel passage irrespective of throttle position (more common in motorcycles, I guess). Though this one seems to be more of a "fast idle." Very enlightening, thank you.

Thanks guys (assuming the above were @ me). I was really pleasantly surprised when I went to go see it. It runs and drives far better than I expected, and needed only minor TLC to become a trustworthy daily driver. Love the fact that it has dealer installed A/C!

Quick picture of my '72 PL620. If the odometer is to be believed (FWIW, I do) it has 51,000 original miles...
