Phenolic spacers

[Michael Oritt]

I am reinstalling the H6 carbs after rebuilding them and I hope to wrap up everything tomorrow. The Moss kit came with two phenolic spacers about 3/8" thick that mount to the outer face of the carburetor bodies, assumedly between the face and the air cleaners.

My car is a Le Mans and cold air box was mounted directly to the carbs without any blocks. Using them would make it just that much more difficult to get the cold air box and the hose and hose adaptor in place. It would also result in the fuel bowl overflow tubes not reaching the grommeted holes in the box.

What function do the blocks serve, are they normally found when CAB's are mounted (as opposed to air cleaners) and if so what harm might be caused by not using them?

Perhaps they act as heat insulators in some applications when placed between the manifold and the carbs.

Michael, the 100M did not come with those spacers between carb and air box. I have not seen them listed in the "LeMans kit" parts either. That carb kit is for all H6 applications, not just the 100M/LeMans, so perhaps there is an application out there that requires them.

The blocks that go between the H6 carbs and the intake manifold are square with four holes.

The blocks I am speaking of are sort of trapezoidal in shape and trace the shape of the carbs' outer face. You can see a pic of the H6 here:
