61 Cadillac Carby help!! Bakerlite plate under carby?
« on: November 23, 2011, 03:08:10 AM »
Hi all, need a plate around 1/2 an inch thick made of bakerlite sits just under the Carby on my 61 Cadillac 390. Anyone got any ideas of where I can get one, as mine is broken in three places, or anyone know what glue to use to get the bakerlite back together and seal it?

See attached picture. Many thanks Milton Watkins.

Both Jeg's and Summit show this type of insulator in there catalogues, but they do not have the channels cut in, they are for what appears to be Q jet carbs, there are other ones listed also.

The '61 spacer is not a Quadrajet type, and therefore will not interchange.

The Channel is there to supply full vacuum passage to either the PCV or Brake Booster (can't remember which), and must be retained.

Bruce. >:D

PS.   The channel cut all the way through is for the Exhaust Crossover to pre-heat the carby.

The parts book lists the same insulator for all single carb set ups from ’57 to 62. I believe this is the type without a PCV attachment port. There is also a metal shim for Carter carbs. I don't recall for certain, but I believe the brake booster vacuum comes directly off the manifold on a 390.

Hi, Thanks for all the members who replied to my question, I think I managed to get one off one of the members off this list, a fair way away, but I can wait till it arrives, as I asked my mechanic to stick my old one back together using sikaflex, so far it has seemed to seal it to a point of perfection, so hopefully it will last till the other arrives, come to think of it, it must of been cracked for some time as the engine has never been this quiet. And my fuel usage should be improved, I use duel fuel, so the LPG is great, $30 for a tank full of fuel and get about 3 hours cruising out of it, should be even longer now.
Regards again to all those that replied, thanks, Milton Watkins, Gold Coast Australia.
