Hi all, engine runs well, however if left standing for a couple of weeks, can be difficult to start and when it finally starts there is a lot of smoke for about 5 mins. (excess 2 stroke oil).this excess oil is also visible seeping from exhaust.Very embarrasing at the boat ramp!!any suggestions?
Re: johnson 70 hp 1999 seeps 2stroke oil from exhaust
hello sounds almost like the oil checkvalve in the OMS pump is bad. or the oil tank cap vent is clogged. my 120 will load up on oil if left to long without running. if I wasnt so lazy I would change the pump. but it gives me a reason to run it weekly
no tech questions by PM, they wont get answered.
