Hummm...as I understood, I need to remove the blade plate (and what ever is under it) to access the bottom crankshaft seal, position the lawnmower upside down, put some 2 stroke fuel on the seal and try to spin the engine

(correct me if I understood wrong)
Will need wife's help to do this - she will have to hold the lawnmower while I pull the cord

Not sure if I'm gonna do this, since engine is starting easily (found that out accidentally after I've inspected state of the piston & cylinder through exhaust hole, cleaned exhaust hole of carbon deposits and tried to clean the scraped material by puling cord - and not previously removing the spark plug cap :D)
Anyway, more concerned now about the state of the piston, rings and cylinder - will post pictures soon in new thread...
Will inspect carb and upper seal first (under the starter)...
Cheers
