Re: 1957 Johnson AD-11 not getting fuel

OK, so the engine has a fuel pump instead of the pressure tank. This change was made by the previous owner, not you, correct? You have only been able to run the engine when you squirt fuel/oil into the carb throat, correct?
You mentioned that the glass filter bowl filled when you initially pumped the fuel bulb, are you saying the glass bowl no longer gets any fuel in it when you pump the fuel bulb? How about removing the fuel line from the carb, then pumping the primer bulb? Does fuel come out of the hose now?
If so, then the primer bulb is working adequately at least. If no fuel comes out of the hose while priming, you will need to look at the tank, primer bulb, fuel lines for restrictions/air leaks.
If the fuel does flow out of the hose while priming, try reconnecting the hose and removing the high speed needle (lower one) from the carb. Now try pumping the primer bulb. Does fuel flow out of the carb? If so, do you have the initial settings set up for the needle valves? The high speed (lower one) needle should be set about .75 turns out from gently seated, the low speed needle should be set about 1.5 turns out from gently seated.
If no fuel flows out of the carb while priming with the needle removed, you have a problem with the float/inlet needle seat, or perhaps a plugged up filter in the glass bowl. Try again with the filter removed from the glass bowl. Keep in mind that the glass fuel bowl will never fill completely with fuel, there will always be some air in the bowl.
