I just bought a new mini rider the man at store helped me get it ready to use battery charged gas & oil I am a 64 y/o widow lady with no help he was so nice I got it home it cranked right up after a few minutes it quit wouldn't turn over do I called Troy built he said check fuse it was OK but...

Hi , I'm a novice at this, so I've done all I can think of. I thought it was the battery, so I recharged it. Still no start. I made sure everything was in the right setting. No luck. I just went out and bought a brand new battery... nothing. I figure I must have the thing hooked up wrong, but...

Mower emits black and then grey smoke when cold started then smoke stops and runs fine after that. Is 21" push mower.

Where is the bolt to change the oil found?
