New Carbarator Heat Shield

[TRIFIK6]

Just saw this on the Moss Motors web site. Anyone have any experience with it? BTW I tried to use the previous model on my stock 72 TR6 but the fuel line was in the way and would have needed to be modified.

I think a lot of guys in 6-Pack have used this shield. I installed one, also - and covered the bottom and inside with heat shield material I got from Amazon. No percolation issues since installed. I also used sticky-backed aluminum tape to secure the edges.

While on this subject, a dumb question perhaps, but when using one of these shields, isn't an extra pair of gaskets required, above the normal count used?

IF there's a chance that using a gasket on both sides of the new heat shield will prevent extraneous air from bypassing the carb and entering the combustion chamber along with the mixture the carb provides since the new heat shield fits between the carb and manifold, then 'yes'.
I see from the description it's recommended to do so.
But with the original heat shield mounted between the carb and 'air box' I didn't deem it that important. I did place a gasket between the front of the heat shield and the rear of the mounting plate for the Longflo air filters, though....none between the rear of the heat shield and the carb's air box mounting flange.
No special reason for doing it that way; at least no reason that I'd want to defend in a debate.

I have the original style, and I use the extra gaskets just in case. I also had no real issue fitting it around the fuel lines. As I recall, all I had to do was loosen the clamps and rotate the lines a bit. I have had this style of heat shield on my car since the 70's, as a guy in my club had 6 made out of aluminum and I bought one of those. Joe Alexander used my original aluminum heat shield as a pattern for his stainless model, and then gave me one of his for my car, and it's been on there since.

I believe that's all I found necessary as well, Irv; loosen the fuel line and rotate it a bit. I even had enough room to slip a chafe guard over the fuel line where it comes real close to touching the floor of the heat shield.

[TRIFIK6]

Unfortunately, I cannot rotate my fuel line as I have the one as shown in this diagram. Look at item #46.
Now my question is, with this new shield which side of the carburetor spacer should I mount it. Closer to the carb or manifold?

[poolboy]

I'd try it on the carb side first.

[bartman]

TRIFIC - Unless I misunderstood your post #7, the shield mounts between the carb and the air filter box. You do not have to remove the carbs to get to the spacer on the intake manifold. It's "easy on easy off" whenever you remove the air cleaner. The only "trick" is needing to find the holes through the air filter box and the heat shield when you put the long screws into the carb body. An extra hand would be nice, but once you get the hang of it, installation is not hard.

CORRECTION: I just looked at the Moss catalog - the version they are selling is not like the one I bought (pictures in Post #2. Ignore my comment about installation.

Last night I tried mounting the older style shield but ran into the same issue TRIFIK6 did, plus an extra issue. Not only does the metal fuel line hang down too much, I have the RATCO cable linkage to contend with. The newer style shield looks like a better solution for my car.
Anyone interested in a brand new heat shield, older style?

[poolboy]

I can't address that particular fuel line problem, Bruce, but the RATCO will work with the old style.

[baws]

Thanks Ken. My RATCO brace between the carbs is slightly different.
Tony sent me the 3 carb bracket for some reason and I had to augment it to get the cable positioned in the vertical.
Hopefully, TRIFIC6 will post pics of his installation as well.

[TRIFIK6]

Here are a couple of pictures of the "older" vs "newer" heat shields. Approximate dimensions "old" 13" x 6", "newer" 15.5" x 8"
These are positioned as looking from the air filter. The "old' one installs behind the air filter and the "new" installs behind the carburetors. Not sure which side of the heat spacer. Unfortunately my TR6 is out getting her (rear end) differential rebuilt so I can't show you the new one installed. Will follow up later on that.

[baws]

Thanks TRIFIK6! I just ordered one of the new style shields from Moss this morning.
I'm going to install it between the carb throats and the heat spacer, with gaskets on both sides of the shield.

[TRIFIK6]

That is my thought as well Baws. I'm sure you will have yours installed before me so pictures would be great. Hopefully there is clearance for the linkage. Should be no issue with the fuel line.
