What spark plug does my mower take?
Ideally, most automobile spark plugs use a thread size of about 14mm thread why those of lawn mower range between 10 to 12 mm. Because of these differences in thread sizes, they just won't fit into the same hole or the unit in which the plug is to be fit in.
Consequently, where is the spark plug located on a Troy Bilt push mower?
Lift the hood of your Troy-Bilt lawn tractor and allow it to cool if it was recently in use. Look on top of the engine to read the model number. It will be either a Kohler or Briggs and Stratton engine with the horsepower listed behind it. On a Kohler Courage engine, the spark plug is in the front of the engine.
In this manner, will a lawn mower start with a bad spark plug?
A dirty or fouled spark plug can cause your lawn mower to not start. It can also work itself loose, causing issues. If the spark plug appears to be seated correctly but the engine doesn't start, a new one may be in order.
