Hey guys,
Im new here but Im looking for some much needed help.
I recently picked up a Johnson 2trk 50hp 1971 outboard and it wont start. my knowledge is not super crazy, and some terminolgy may be slightly inccorect.
Iv checked spark plugs which both work well, theres seems to be presure in the combustion chamber (i dotn have a preaure meter thing to put inthe spark plug fitting) however when turning the motor slowly there is presure build up.
I have fully cleaned the carbs (not changed fuel lines) and the motor still doesnt start. There is fuel coming through the carbs also.
I have also tried start the engine by just spraying fuel directly without the crbs on to see anything. Once in a while htere will be a nice big pop but no real luck.
What im thinking is that the gasckets between the carbs and the engine block are too old and are letting too much air in while starting, and not only that the gascket of the airbox has a small gap which allows more false air in.
there is a new battery hooked up, and everything else seems to be in working condition.
What do you guys think?
(please dont respond if your responce is: get a new outboard
