Herein, where is the spark plug on a lawn Boy lawnmower?
Locate the spark plug(s).
On a walk-behind or riding lawn mower, they're usually near the front of the engine. On zero-turns, look near the back of the engine on the sides. Disconnect the spark plug lead and clean around the spark plug to remove any debris. Remove the spark plug using a spark plug socket.
Simply so, how often should you change the spark plug in a lawn mower?
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.
Lawn Boy calls for a 32:1 gas/oil ratio when using its own brand of two-cycle engine oil. That is equal to 4 ounces of two-cycle engine oil per gallon of gas. Toro two-cycle oil can be used in place of the Lawn Boy brand, the company says.
WD-40 removes carbon residue and keeps moisture away from spark plugs and spark plug wires. WD stands for Water Displacement, so if your spark plugs are wet or you need to drive moisture away from ignition distributors, for example, WD-40 is a product you should have handy!
When a plug is fouled it gets coated in some substance like oil or carbon. This prevents the plug from sparking correctly. A spark plug can be cleaned and reused, but it more than likely won't run at or near the same efficiency as before it was fouled.
