I'll let others comment on the mark.....
You should take the caps off both sides of the advance can if you are not going to use it.
Why? If the advance is not being used it should not matter if the ports are capped or open.
Jim
Never ever cap your advance even if you are not using it. As McMark says - tell your friends
Sorry but I don't see a reason not to.
If you are just using one side of the vacuum canister then you shouldn't cap the other side air needs to be able to go in and out of the unused side.
If the vacuum advance is not used, then capping either or both sides will have no impact on any other function of the distributor. The mechanical advance does not move the vacuum advance mechanism.
Jim
It will limit the advance plate unless the arm is disconnected with the little circlip.
But if you are running carbs why use the stock dizzy?
Get an electronic programmable dizzy and don.t look back.
IMHO
I agree if you are using Carbs and no vacuum advance, why the stock distributor.
I was trying to understand your reasonong for "Never ever cap your advance even if you are not using it."
If you are not using the Vacuum advance then you actually want to limit the advance plate, it is only used by the vacuum advance. If you disconnect it from the vacuum canister then it would be free to wander around within its range of movment and your time could be very inconsistent.
But you do not need to cap teh ports on the vacuun canister, just leaving it connected and the ports open will limit the advance plate via the springs inside the vacuum canister.
The mechanical advance is done by weights and springs under the advance plate and it rotates the top of the distributor shaft, moving the cam that opens the points, in relation to the points.
