yes, it should have a small amount of play, When The Distributor Is Installed !
it doesn't matter how much play it has when it's out of the engine, it can be ridiculously sloppy, it doesn't matter until you snug the clamp bolt
the less play it has outside the engine, the more I would worry. when you snug that clamp bolt, it can only have the same free travel or likely less, possibly none or negative
what I did was set the new gear intentionally low on the shaft, with the pin holes in alignment and snug the dizzy down with the clamp bolt. now remove the dizzy & inspect the pin hole. I found that snugging the dizzy down set the pin hole in the gear ABOVE the pin hole in the shaft. the clamp bolt was jamming the gear down onto the block ledge with no oil clearance, causing drag. measure where the snug down set the gear & raise it the amount of oil clearance you want higher on the shaft. a new hole will need to be drilled in either; only the new gear to use the original hole in the shaft, or drill through the new gear and the shaft, 90* from the original. I drilled only the new gear to use the original pin hole in the shaft
don't get me started on rotor phase...
