Thoughts on this?

Another question: I have the idle stop bracket for the carb, but what solenoid does it take?


Thanks for the Photo link James...great stuff!!

Yes, 437-15 is the vacuum advance pod,
In reference to the 536 advance - I was referencing the mechanical advance mechanism inside the distributor.

The solenoids run $40 - $100 for a NOS one. I bought a NOS one recently for $40.
Here is one for $42.50

It plumbs between the carb vacuum and the distributor, all of it operates correctly on my car.
For the CEC (combined emmissions control) to operate - There are 2 reversing solenoids(located on the firewall, off center on the drivers side mounted back to back), the twin prong temp sender on pass side head, & the trans switch on the 3 4 shifter boss along with the carb vacuum break solenoid.
