I have a 90 Merc 200 it idles fine and the bulb pumps up but when you take off it stands up then wants to croak. If you pump the bulb it seems to help. Shouldnt the bulb stay hard all the time after pumping it? Once it gets up it runs but is down on speed. It acts like its flooding because if you reve it before take off it smokes bad then helps. But im confused because the bulb loosing prime would make me think lean, plus the fuel filter doesnt fill up compltetly and if you pump it up and let it sit the fuel filter empmtys after a while. Plus the last time I check the plugs look wet. Ive checked the plugs, boxes coils, and cleaned the carbs twice. What am I missin? Thanks guys! And and lassies that might be out there. I also forgot to say that it seems to use way too much fuel all around.
