Hello / I am putting back my carb on my original nailhead. Do I have to install the gasket between the carb and the manifold dry or should I put some liquid sealer or grease on the gasket? Also / can I put the sparecarburetor ( 2nd picture ) on my 401 nailhead? Thanks and have a nice day / Herby
I dont have one handy, but it's shaped exactly like a carb gasket only made of thin stainless steel. it shields the carb base from the manifold heat from the exhaust, and is installed directly to the manifold. If you run the car without one, the exhaust gas and heat eats away at the bottom of the carb - not cool! So the order is: heat shield, gasket, carb with no other sealers or anything. You wouldnt think the heat shield would seal against the manifold so well, but it does. I know that Carmen Faso at JC's Parts in Buffalo NY has them in stock, he's at 1-716-693-4090. So does Centerville Auto in California at 530-272-1564, and he takes credit cards. The 2nd carb looks like a 4GC, but I'm no expert. It will probably work, and long as the linkage arm on the base has a 2nd attachment point for the kickdown switch (assuming the car is equipped with a Dynaflow and it uses one) Good luck and dont forget to post pictures.
Can't I just close the heating holes with screws, so the aggressive stuff from the exhaust will not come up to my carb? ---------- Post added at 05:34 PM ---------- Previous post was at 05:32 PM ---------- and yes / I will sent you pictures when I continue working on my engine!!! Thanks for the kick down idea, I have to check!!!
Yes. I used threaded brass plugs. I cut the square heads down for clearance and slotted the top to run them in with a screwdriver. Once done I covered them with a two part epoxy putty called JB weld and filed it flush to the carb pad. You can see the plugs in this picture.....
