spacer or not?

[mbouse]

i just checked the only known phenolic Fiat stock spacer i had laying around. it is roughly 4mm thick. quite thinner than i remembered.

the phenolic spacer along with either a 1" or 2" aluminum spacer would be lovely

yeah, but the boyz in the shop are getting cut back... taking a government job into the machine shop now would be suicide.

i just measured. i have three inches of clearance with the current setup...which would be great for a 2" aluminum spacer with the 5mm phenolic.

there's always next year.

2" spacer with the gasket would be better

maybe this winter i get to learn how to run a Bridgeport.

I can't make any promises but if you get me a dimensional drawing of what you need I can probably get one made for you. All it would cost would be the material and what ever bribe I would have to pay for the guy in the shop to stay over/come in early and I would certainly let you know first. Let me know.

thanks for the offer. i have the identical situation here, except i am willing to crank the handles on the Bridgeport myself occassionally. So, i buy the material wholesale w/out sales tax via the company's vendors and bribe my die maker...also gives me a chance to talk to my fellow employees on a non-work level, which is always beneficial.

[So Cal Mark]

avoiding sales tax? You're starting to sound like the large corps that have moved off-shore! Oh Mike, and I thought you were a good American
why not make the spacer from a good hardwood? remember that discussion in another thread?

[mbouse]

i do recall that discussion, and wished to forget it.

wood is for interior cosmetics, or LBC's

not for Italian mechanicals

Mike,
Try to get your air cleaner level with the top of the carb like this: http://www.flickr.com/photos/bigtimes_fiat/2849182986/

Then add your spacers between the carb and manifold. Phenolic may be hard to find in a 1.5"--2" inch thick piece. You may have to epoxy two thiner pieces together. Derlin should be easy to find in any thickness.

BTW when are you going to combine your two threads?

Here is the spacer I was thinking of: http://cgi.ebay.com/ebaymotors/Holley-W ... enameZWDVW

A bit pricy.

Mike. get the machinist at work to fab one up!

Cool ideas, might be interested in trying the spacer idea. Here is the technical question:

If you make or buy a spacer should it have the same size holes in it that match the 2 throttle openings or should it be a single oval opening to match the intake manifold? Which design gives the best improvement of air gas mixture?

Any ideas?

[So Cal Mark]

I would match the single hole in the manifold

[mbouse]

well, I agree with mark... however fiat did not for the 28/32 weber .. if not other carbs, with two circular openings just big enough for the carb.
