I have a loss of water pressure coming out of my pilot water hole. This is not the first time it has occurred. I cleaned the carb and plugs because the first time the carb was letting out to much gas and it worked o.k. this time I tried it and it didn't work. When on the water I tried bouncing the outboard back and forth and it worked. The water discharge hole works fine and now seems to put extra water out. The engine is running a little rough but does not seem to different than before the problem. Anyone have an idea to whats causing this?
