Do you have multiple primer bulbs? What do they look and feel like when the thing is misbehaving? If it's an upstream blockage, the bulb will usually collapse. If it's downstream (towards the engine) the bulb should stay round, and pumping it *may* get the engine running better.
Another thought is whether you've got new bulbs. If they're Tempo products, they should be immediately suspect (the one I got for my 14' Achilles/Honda 40 wouldn;t even pump air.)
Is your fuel line set up with a single hose from tank to transom and then a short jumper hose between engines? If so, replace the jumper hose. Easy to do (especially since I won;t have to), and eliminates the question of that component.
