My Yamaha Pro 50 hesitates out of the hole, unless she's been running for a while. I can choke her back to health, but I'm a bit concerned. The fuel pump is new, so I hope that's not the answer. Is there a fuel/air mixture screw easy to reach? Could it be the bulb/fuel line off the tank? Should I get some Yamaha fule additive?

I don't have a manual at home ,but I believe there is a idle nedle on the starboard side of the carb.
