My family's old mower won't start no matter what we try, new gas, new oil, new spark plug. What other reasons cause it to not start? Is there a battery that make the spark plug sparking like cars?

My family's old mower won't start no matter what we try, new gas, new oil, new spark plug. What other reasons cause it to not start? Is there a battery that make the spark plug sparking like cars?
No... what kind of mower? Riding.. push.. a battery would only push a starter.. what about air? How long has it been sitting? Air cleaner? Record with sound trying to start..
No battery. Most mowers are magneto off of the flywheel. Usually their timing does not shift, unless the blade struck something.
A variety of reasons it may not start, gummy carb, plugged fuel line, plugged vent in the gas cap, plugged air filter etc.
Systematic approach: are you getting fuel to the cylinder- spark at the head-compression decent.
A whole mess of reasons that are hard to diagnose on da webz!
Is is a pull start or does it have a starter motor to crank it over? Most likely it's a dirty carb from old gas sitting in it.
There probably isn't a battery. If its getting a spark, it sounds like its not getting fuel. Maybe take the carburetor apart to see if its blocked?
It's a pull start, I'm very curious if it doesnt have a battery, what creates the spark?
Like BP said there is a magneto on the flywheel that generates electricity when it spins. Did you check for spark?Quote:

No, I can hold the spark plug and no shock, took it into the dark, no spark.Quote:
