The spark plug gap is an area of open space between the two electrodes of the spark plug. Proper distance for this gap ensures the plug fires at the right time to prevent fouling and early ignition of the lawn mower engine.Know More
Manufacturers design small engines to operate using different spark plug gaps. Two mowers from the same company may operate with a different gap. According to Briggs and Stratton, the owner's manual for each device provides the information on the type of plug to use and the gap setting to use with it.
Manufacturers pre-gap plugs to the specifications set for most small engines using them. However, being bumped during transit can sometimes affect the gap. Some engines that require a specific plug need a different gap than what is preset at the factory. Setting the plug involves the use of a wire feeler gauge. Choose the wire on the gauge according to the size of the gap the manufacturer specifies. Adjust the electrodes so the wire moves through the gap with a slight resistance. The tool includes a hook that allows users to widen the gap if necessary. If the gap is too wide, close it by pressing against a soft surface. Make small adjustments and check with the wire to ensure the correct distance.Learn more about Outdoor
It is possible to jump start a law mower from a car. However, some lawn mower manufacturers recommend not jump starting mowers that have fuel injection, due to the possibility of damage to the electronics. If such is the case, then the battery must be removed and charged.Full Answer >
Engine oil for lawnmowers is recommended based on the average outdoor temperature at the time of use. Colder temperatures turn the oil viscous. For non-freezing weather where the temperature rarely falls below 40 degrees Fahrenheit, SAE 30 or 10W-30 oil is recommended. For colder temperatures, 5W-30 is recommended.Full Answer >
Replacing the belt of an Ariens Lawn mower begins with disengaging the mower to allow for slack on the belt. Do not turn on the machine while replacing the belt. Disengage the deck from the control rod, and then pull the old belt off the three pulleys. Replace new belts around the mower's pulleys following the same configuration as that of the old belt, and replace the grass catcher.Full Answer >
To gap a spark plug, use a spark plug adjustment tool to gently bend the bottom electrode of the spark plug toward the other electrode to narrow the gap or away from it to widen the gap. Before adjusting the electrode, test the gap's width using a feeler gauge.Full Answer >
