Vacuum actuator

[Roger Zimmermann]

3-carbs set-up used from 1958 to 1960 have a vacuum actuator to operate the front and rear carbs. Is this actuator still available or should it be repaired for example by Terrill machine?

The turn up occasionally on eBay but a used or even NOS can have weak or hard rubber inside. It's just a big diaphragm inside.
The unit has a rolled or crimped edge and Mike Rizzuto from Mastermind Inc rebuilt mine and has the machine to recrimp the unit back together.

I'd go for the repair with the fresh rubber.

Thanks for your comments Brian. Mike is a good guy but expensive; I will ask Terrill if he can do it as I know he is rebuilding vacuum advance systems.

Please report back on Terrill.

I got mine done about 5 years ago. I think it was about $200.

Terrill machine is not repairing them because the diaphragm could be a molded part. Therefore, I will ask Mastermind.
