You won't move a lot of air in the best case because the tube is so small. Any air movement is a good sign. Are you checking for oil flow by cranking the engine using the starter? Or are you starting the engine temporarily & checking the flow? If you are using the starter it'll take some time for the oil to reach the top end. Even with the spark plugs removed to let the engine turn faster it'll take several seconds of steady cranking for the oil to get to the top. I point this out because you may be thinking you have an issue when you really don't. If it were me I'd start the engine and let it run for a few seconds. With it running oil will get to the top very quickly (2-3 seconds) if you don't have a restriction. FYI it takes my '38 about 10-12 seconds of steady cranking without spark plugs to get oil showing at the top.
