Johnson 55 sea horsie issues
I've got this late 70's Johnson 2 stroke 2 cylinder which I am working on.
I did a testrun on the muffs lately, but the engine won't run at idle at all. It hasn't run in a long time, so I took appart the carbies, cleaned them, and replaced some fuel lines as well. Set both idle & WOT timing and did a testrun on muffs again.
It ran just as worse as before, coughed like crazy, sometimes spit back through the carb's and generally running irradic and smoking a darn lot. Also, the motor keeps leeking this black, oily stuff through the exhaust while running, deff two-smoke oil.
Adjusting carb's didn't do much, the engine just dies out at aprox 1500 RPM everytime, according to the inductive tacho.
Cleaned the carb's once more, and inspected the reed valves manifold as well, but all to no avail.
So the timing is set, carb's are fine, get and hold it's fuel, Reed's are OK and compression seems normal and even on both cylinders. My next guess it's the ccrank lower- or upper seals...any other ideas on this?
Thanks in advance,
