Gasket for secondary carb cover

[mbrick]

Before I remove it, can anyone confirm which gasket is used for the dummy fuel inlet cover of the secondary carb on stock dual 38's?

The fiche lists 2x filters so I know there is one in there, but does not show the cover removed. I'm guessing oring #19 because it says qty 2, and no fiber gasket.

Before I remove it, I want to confirm the gasket is included in the Mikuni rebuild kit.

Incase anyone was wondering here is what it looks like. As I suspected it only requires the #19 o-ring.

Found a little bit of debris in the filter, same as the primary carb. Not enough to restrict fuel but at least I know it is a fresh filter now. Both the o-ring and filter are included in the Mikuni genuine rebuild kit MK-BN38/44-SPR.

I am super confused about this as well. So part #20 is only used in the fuel pump carb next to the #19 o-ring?

Correct. The non fuel pump carb only has #19 o-ring under the 'dummy' pump cover. No flat gaskets.

The o-ring probably would have been fine in my case because it still appeared to have a decent amount of compression and was not totally flat like the needle seat o-rings end up. #20 is serving as part of the fuel pump functionality for the check valves so after I looked at it more it makes sense it is not needed on this side.
