how do you set the floats in the carbs? i am working on a 91 evinrude 120 v4. boat runs but will bog down sometimes and when i stop to fish and try to start of again it is like the carbs are flooded out. it sat up for several years before i bought it. it ran good for a couple of years and it started all of this. checked stator and trigger they both checked out good.

Start with the basics. Check your compression and then your spark which should jump a 7/16" open air gap on a spark tester.

Does your primer bulb hold firm with engine off?
