I inherited an older Montgomery ward lawn tractor am attempted to start it, new battery in place but believe it may need a new spark plug, I can't seem to find where it's located? The engine is a Briggs and Stratton 14 HP Model 287707 Type 0153-01 Code 9304154A, I have no manual, any assistance would be great?

Mr. J Vaughan, do you happen to have a link to the schematics or manual for this model?

It's under the muffler.

I believe that this should be located at the very front of the tractor I looked at a schematic for this engine and it will either be at the very front or the very back.
