TC Carb. body warpage

[davjak@aol.com]

Checked the archives and did not find anything on this.. Just like in TCs Forever, I found warping in the mounting flange of my TCs carbs. Anything short of carb body replacement? I could fly cut the surface but that would probably create an even easier (thinner) to warp surface.. Presently they noticeably rock on a flat surface.. Thanks, Dave [Non-text portions of this message have been removed]

You could cut a groove in both sides of the heat insulators that some have fitted under the carbs. These would accommodate a pair of o-rings, then use spring-washers with nyloc self lockers on top. Like the anti-vibration Weber set up. Best, Ray "Morology is our profession, our ONLY profession!"

Dave, usually when you see the flange warpage this is due to over tightening of the bodies. You will also find the the bore around where the throttle disk sits is also out of round allowing air to leak past. The only way to cure this, other than buying new bodies is to bore out the body and press in a sleeve then bring that back to size. Phil Marino does this repair.

Dave, flange warpage can be fixed easily by laying a sheet of 220 wet sandpaper on a flat surface ( wife's countertop) wetting with marvel mystery oil. Hold the paper with your left hand and put the carb body flange to the wetted paper. Rotate the carb in a figure eight pattern with your right hand , not pushing down so much as rotating and machining lightly . You will see the high points on the flange appear dull as the process works to flatten it out. You may use a few sheets of paper to do this , but it is quite simple and a lot less expensive than replacement. Kevin Brinkerhoff

Here's a thought : !) Do whatever is necessary to get a reasonably flat surface on the mounting face of the carb. 2) Using either steel or hard aluminum plate of about 1/8in. thickness, fabricate a plate to fit between the carb and the manifold. (Could use a gasket as a pattern for this) 3) Epoxy this reenforcing plate to the mounting face of the carb body. 4) Mount carb as usual, or with thicker & softer gasket The idea here is that the new plate would supply the rigidity/strength that's lacking in the carb flange.

Any honing off of the carb mounting ears just makes that area weaker and more prone to warpage. If a reinforcing plate was used, I am not sure how that would differ from bolting to a solid manifold to begin with. Would the epoxy be strong enough to stiffen the two parts and remain rigid enough? Use of a softer, thicker gasket only compounds the carb ear warpage as you tighten the ears down so don't do that. I understand the TD carb bodies were good replacements for the TC ones as they were made of stronger aluminum rather than the weaker TC bodies. That seems like the best way to go. Just swap that part out. And if your flange is bowed the carb throat may be ovalized as well. Phil Marino did do a carb throat sleeve service at one time. He has cut back on his services so don't know if he still does this now. His phone is 951-352-4419. That is in a California time zone. He does not do computers. By the way Phil is selling off all his tooling for the tapered axles. It is a good deal for anyone wanting to produce these and includes all drawings and the special form cutters for the splines.

All you are doing is "facing" the surface , not removing enough material to thin the flange appreciably. If done carefully the carb doesn't need to be disassembled.

I used a thick flat glass plate to spread the sandpaper.

Hi All, the reference is obviously to Sherrell's Chevvy fender mouldings. A friend repaired mine by squeezing (in a vise) a socket of the correct diameter. This gave a round orifice and the butterflies sealed properly. Sounds drastic but the pewter from which they are made is fairly malleable. Clem TC 7218, Durban, South Africa.
