Motors that have a fixed high speed jet must have the gasket installed, as any leakage through there is added to what is metered through the h/s jet. Motors that do not have a fixed jet (has adjustable needle) do not require a gasket but it won’t hurt anything if you do install one. Adjusting the needle is perfectly capable of compensating for any leakage past the nozzle.
Now, this discussion is about the Big-Twin series carburetors. The smaller motors (20hp and under) are a different story.
