Sorry for the vague title and the non gear head description, Im not much for working on small engines other than a carb rebuild here and there on a weedeater or chain saw .. So heres the chain of events... I started mowing this morning and made 5 or 6 passes through my side yard, the grass was kind of wet but not very thick so it wasnt clogging anything up, and all of a sudden the sound of the motor and output changed and I shut it off. Tried to start it and it wouldnt. It seemed like it would turn over just not fire.
Heres what ive checked/done: Full of oil and gas (The slingblade does not apply here), spark plug was very black, so i changed that. Cleaned around all the pulleys and belts.
Again I apologize if the description is to wide or vague and thanks in advance for any help. It's an 18.5 B&S motor thats only got 43 hours on it. Heres the shitty part, warranty was 24 months; I have owned it for 24.5 months.
