Hello Guys. I found an old Lawn Boy on the side of the road (left there for trash). I can't find any information on this model. The tag says model 5239A and serial number is 55653. Manufacturer is Outboard Marine Corporation of Canada, Peterborough. It looks like it was recently used, clean air filter, still has gas in the tank. Problem is no spark. I cleaned the flywheel pads for the coil. Removed spark plug to check and no spark. I tested the plug in my other mower and it is good. Shows a spark. Champion RJ12C. No idea of what the gap should be. So, I'm thinking it must be the coil. Is there a way to test the coil before I buy a new one that may not be the problem? Anyone know where I can find info on this mower? Lawn Boy site doesn't recognize the model and serial numbers. Thank you for any info you can supply. ... Glenn.
