I have a 1999 150 hp johnson ocean pro, at the end of last season i noticed that i was have a harder time starting and excessive smoke ( blue ) on first start up of the day, when the motor is running i have no problem with it, good rpm and and very little smoke at all, when i pump up the fuel bulb it get very hard, after start up it is a little softer, last year i put a micron filter on the fuel, when i went to start it up this season it gave me a hard time starting when it did it smoke a long time and it look like oil streaks out the exhust, there was also oil in the cowl, any help would be greatful ....
