Hello. I have a 1985 johnson 70hp that I can't seem to get running. I just dewinterized it to weeks ago and in ran great for the last two weeks. After running fine all day I noticed it losing power while I was at full throttle. I barely made it back to the dock.. I have replace the spark plugs, Checked to make sure the plugs were firing. Rebuilt the Carbs, replaced the gaskets, Fuel pump is new.. The weird part is that after I rebuilt the carbs, I muffed it and it ran great, idled perfect while it was in the driveway. When I turned the motor off. It was real hard to start again, and now I can barely get it started. anybody have any ideas?
