I tryed out my startos tonight that has a 96 150 mariner. It starts fine,,but smokes like crazy and wont put the rpm`s up and boggs down. I can put in N and rev it up till it clears then throw it in gear and it`ll put up then all of a sudden it`ll take off and run for miles,,runs great and smooth till ya drop off a plane and starts that smoking stuff again...any Ideas?
