- The 78 B tunes up fine and I can even get the idle set to specs, but there seems to be a buildup of vacuum at the distributor. After driving and getting up to 4th, the idle goes up to 1200 from 900.

- As an emissions measure the distributor vacuum takeoff was moved from the carb to the inlet manifold. This gives maximum vacuum at idle instead of no vacuum and increases the idle speed, allowing one

- Thanks again for your accurate descriptions of how things are supposed to work. I pulled the TCSA solenoid off of the pedal box to clean and examine it and found it to be working properly. What wasn'

- Now I'm a little confused...I thought the solenoid was either open (in 4th gear) or closed. How does hooking up the vacuum lines reversed change its operation? In any case, I'm planning on reconnecti

- My TCSA has 2 ports 1 vertical and the other horizontal pointing toward the front. The horizontal port is vented out the bottom of the solenoid when not actuated and connects to the distributor. The

- As I mentioned before the solenoid closes off the port from the manifold but opens the port from the distributor to atmosphere to allow any existing vacuum in the capsule to dissipate. Bypassing the

- Oh, that's my fault for not looking at the actual solenoid before writing my post. So the top port goes to the manifold and the horizontal port goes to the distribuotor? I guess that's what i need t
