Title: Linkert
carb flange gasket

What seems to be the common or best way of mounting the linkert carb, with the thicker isolator gasket, or two thin gaskets on each side of the metal plate, surely you guy's have the answer. Cheers Gearbox.

hello,
I have had the thick gasket and the thin ones over the years and they both work about the same. as in they sealed okay. is your carb mount face flat and not warped.
did you check this?

Thanks for the reply Mbskeam, I will check out the intake flange and carb flange for straightness. I should have just bought a intake tester from you, by the time I rigged up all the pieces and used a piece of plexiglass, I could have saved alot of aggravation and been done with it. Would you be interested in selling just a aluminum Linkert plate, do you thread your plates or just bolt to the intake with nuts and bolts? I'd like to scrapp this Plexiglass,not sure if its sealing. First thing I'll check the flanges with a feeler gauge and straight edged, what do ya figure the allowable warparge would be?

The phenolic spacer with dual gaskets was introduced in -48 and assists a proper alignment with the support, among other things. Removing it may cause (besides purists pointing their stink finger) a tweak of stress on the assembly, promoting future leaks. (The support should always be massaged for the best mating of the carb to the manifold after the manifold is sealed.
Note also that a different bolt length was used.
The disadvantage of this design is that the spacer does not offer much support against fastener distortions. Avoid over-torquing, and most carbs need the flange dressed to flat beforehand. A few swipes on a flat abrasive surface tells the story.

I don't know as much as the previous guys, but I got to give up one thought - re the plexiglass thing. That material does not compress and I think it is sort of like a metal to metal seal, or worse. So I would get ride of such a material and go with normal spacer, (about $15) so as to get a good and compressable seal.
Hope this helps.

hello,
kickstart....
the plexiglass thing being talked about is for pressure testing the intake for leaks. not as a gasket

I use a thick sanwiched between two thins, I think...have to go look to be sure. Get an intake manifold test kit from Mbskeam. I did.
