Hello -
I have a 90hp 4-stroke that I have only used a few times a year. It has always ran well, but when I tried to winterize it last fall it wouldn't start. I can pump the ball and get gas to the carb side of the fuel pumps but nothing gets to the carbs. The ball is very stiff and I have pressurized fuel at the exit of the fuel pump. Is it possible that all four carbs have floats that are gummed up and are not letting fuel into the bowl? When I remove the drain plugs on every carb they are completely dry. If it was a gumming issue I wouldn't think that it would happen simultaneously to all four carbs. I am about to remove the carbs to clean/rebuild them but was curious if anyone had any other ideas for me to try before I rip into it.
Model # of engine is 1F90412YD
Thanks!
Mark
