ok I have sourced a 1970 transducer for my 64 climate control. told it would work.
it does but I need to adujust it and unlike the 64 transducer that had the screw
adjustment at the bottom this one appears to have none. at 65 degrees its getting
8.6 volts but still holding 7 inches of vacuum - still too much for the power servo arm
to move far enough forward to actuate the mode control so the AC comes on.
any ideas how to adjust
cheers

thanks David. I actually reparied the old one - did not think I could but the 64 transducers are not that complicated - refitted and it works as well.
Thanks for the replies. here is an update. the 64 transducer I got had the ports around the wrong way to I mounted it above the vaccum lines behind the glovebox successfully and ran an earth wire to the chassis. This transducer did not seem to work properly thus I got the 1970 one. I sat it on the glove box door with the same earth lead and the same issue seems to have been happening. so after so thinking I checked the continuity of the earth. 4 ohms. !! new earth and the 1970 transducer works jsut right. 4 inches of vaccum at 65 degrees and 14 inches at 85. all good.

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?

Hey everyone, has anybody done a Vintage Air AC/Heat setup in their car? I want to bypass the old vacuum setup and go with a Vintage Air Gen 2 model. Before I get started, does anyone have any experience with this? (Which model to go with, do’s and dont’s, etc.) It looks pretty involved. Any and all info/pics would be greatly appreciated. Thanks!

My son, unbeknownst to me, had all three of the horns on our 1963 Eldorado completely restored. We had recently added the Eldorado trumpet horn to the two standard horns and the sound was not very good... we had heard good ones so we knew something was not right... but there was not much we could do to get better sound from the 3 horns.
There is a restoration service called The Horn Works who my son…
