Yes, they do. I think there are also ones available without, though.

You can also get the paper gaskets separately, but i highly recommend using the thicker phenolic spacers, even for carb conversions ...

Ok, I'm going to ask a stupid question: I replaced my intake runner gaskets a while back with the Reinz product (I don't think the one pictured above). Was I supposed to use something else as well? I'm not familiar with phenolic gaskets. I have stock D-Jet...

Thanks for posting this... I have a set of phenolic spacers to install on mine and was thinking that I needed to order gaskets for both sides, now I know better

Phenolic is harder than the gasket material. I recommend that you use 2 gasket on each side ;-)

i think the above reinz ASSY pictured, is a phenolic spacer with a gasket on both sides.

so an order for 2ea assy should be all that is needed.

Just to clarify, with dual carbs, IDF's or DRLA's, use the phenolics because they'll keep the fuel in those carbs from heating up and even boiling. But with a center mounted carburetor you really DON'T want to use phenolic spacers. Reason is that with that long run from the carburetor to the head the runners tend to ice up in hot weather and fuel mixture will form droplets. Means it's a good thing to get some heat up into the runners, and no worry because the fuel in a center carb is too far away from the heads to ever get hot enough to boil the fuel in the bowl.

I know that may be a bit counter-intuitive, cool dual carbs, heat a single carb, but that's how it works.

thanks DB : )

I have had dual 44idf's on my car for eleven years without the phenolic spacers and have never had an issue.

Means you have a well-built engine so it ran cool. But get the timing off, mixture a bit lean, restrictive exhaust, cam not well matched to the heads/exhaust, etc, etc in the summer and you'll run it hot and cook your fuel. So good job on that engine. (eleven years... engines?). No big deal, most of us have a set or two in a box somewhere, so use them. Cheap insurance.

Close, but not quite there. It's actually: Cool dual carbs, throw away single carbs.

You know Dave, I've repeated your "float test" for single carbs a number of times. Best explanation I've heard, so thanks. In this case it's temporary, so it's OK, but when he's done he can do the float test himself.

Who sells the paper gaskets separately?

Posted by: stugray Jul 1 2015, 07:20 AM

I only used the paper gaskets when the spacers were new.
Now I just put a thin coat of RTV Blue on each side of the spacers.
