reamer Posted August 18, 2019 Share Posted August 18, 2019 Since the carb is out for a rebuild, it stuck in my mind that it was mentioned "you should be getting more that 15" So broke out the mighty vac, surprisingly enough the whole Vac controlled AC/Defrost system is holding steady, I found the cruse control-controller is leaking, I plugged up the other port going to the dash for the brake pedal dump, so its in the Controller its self, but is it supposed to hold?

Gary Lewis Posted August 18, 2019 Share Posted August 18, 2019 I don't know for sure, but I would think it is supposed to hold vacuum. I'll try to remember to check tomorrow. Link to comment Share on other sites More sharing options...

Thanks Gary I do know it functions properly, but it might be the beginning of a wear tear..... Link to comment Share on other sites More sharing options...

Yes, the cruise servo should hold vacuum - it's similar to the brake booster.
