Hi there I'm new to the forum. I just bought a 91 b*** cat with a 91 evinrude intruder 150.and am having a few problems. First when you squeeze the primer bulb right as it gets hard fuel starts leaking out of the bottom 4 carb mouths it does start but some times it takes almost full throttle for it to fire and some times it fires up and idles great ? Have done a compression test results were 90 on all cylinders. Any help appreciated
