I have a lawnboy gold series walkbehind mower with estart and rear propelled.it has the 5hp commercial grade 2 stroke motor and all aluminum deck.where in the world is the model number and serial number? for the life of me I cant find it.nothing wrong with this beauty as I got it off a friend who accidently ran straight gas and seized it ,so he went and bought a new mower and threw this one in the junk pile.well to make my story short I took it home ,took the plug out ,rapped the piston with a hardwood dowel and away she went.offered to give it back as repair time was 1 minute but he wouldn't take it back so ive had it for 3 years trouble free now.mainly want to know when it was made .im quessing 1990,s as the dealer is gone since then where they bought it.on a side tangent I use to have a white omc lawnboy with the famous d-400 2 stroke until I ran it over and flattened it .boy was I mad .that little 2.5 hp 2 stroke would cut grass as thick as all getout and used almost zero gas.my green bomb is excellent on fuel also.
