What is with this continuing discussion about an idle solenoid?
He has not mentioned any dieseling or run-on since the very first post.
The videos are not great, but I cannot see that it ever had one. It's a '69 and the only emission system visible is a PCV system.
I don't recall any '60s engines with idle solenoids other than small displacement engines with Air Conditioners. They operated only when the AC was on to keep the engine from stalling at stop signals because of the then high compressor loads..
Idle solenoids were common in the late '70s when the engines had multiple EPA mandated emission systems and brand new engines couldn't run without one.
