The reason I asked is because I did the same timing exercise as you with my 76 speedy .
It ran for 47 hours without the chrono, 42.5 hours with the chrono running. After stopping the chrono it restarted and is still running over 3 hours later.

Okay. I’ll try again and see what happens then report back. Any excuse to tinker.

Yeah, 2.5 hours more after stopping the chrono.
