A leaky crankcase seam would still cause problems, whether you squeeze the primer bulb or not. So it would make no difference. You need to get the carburetor and fuel pump squared away before proceeding further, otherwise your just chasing your tail. I’m thinking you may not even have any leaky seams at all. if the carburetor inlet needle is still original, I can promise you that it needs replacement anyway. As for me, I don’t even try to start a newly acquired outboard without first checking the compression, and if that’s good, then go through the points, condensors and follow up with a carburetor cleaning and rebuild. Lastly, of course, go through the water pump and gear lube. Then you will have a dependable motor that will run for years to come. Here is a picture of a block with the crankcase halve removed, for reference. https://www.ebay.com/i/112836155110?chn=ps
