Whether you start the engine with a pull rope or the turn of a key on an electric start motor, you are relying on the ignition system to produce a spark inside the combustion chamber.
When you start your lawn mower or small engine, you turn the flywheel and the magnets pass the coil. The most common starter is the one that comes with your car or truck. It’s called an automatic starter because it automatically starts when you push the starter button. Automatic starters are available in a wide variety of sizes, from 1/4-inch to 3/8-inches in diameter.
You can also buy starter kits that are designed specifically for your vehicle.

Should Choke be open or closed when starting lawn mower?
The choke lever is closed at start-up to restrict the air intake in the combustion chamber. The choke is open at the end of the stroke to allow the exhaust gases to escape and solve the problem of getting fuel and the engine heated up to operating temperatures.
When starting a lawn mower with a choke, the throttle should be opened to the full open position before starting the lawnmower. If you are not sure of how to start a LawnMower, you may want to read our article on starting Lawnmowers.
How do you drive a lawn mower?
Use the shift lever to put the mower into low gear after lifting your foot from the brake pedal. It’s pretty much like steering the wheel of a car when you press the drive pedal. The mower should be driven across the lawn.
Is it hard to start a lawn mower when it’s cold?
The oil is one of the main reasons why a lawn mower can be hard to start. Life is difficult for the engine as the temperatures drop because of the poorer oil flow.
How does a small engine start?
The magnetic field induces electricity, allowing the ignition coil to send voltage to the spark plug. This mixture is then ignited by a spark. The spark ignites the oxygen in the air, causing it to ignite the gasoline and create a flame. As the flame burns, it creates heat, which causes more fuel to be burned, and so on, until the entire combustion cycle is complete.
What is the choke lever on a lawn mower?
A cold engine starts smoothly if the fuel mixture is enriched by a choke or a primer bulb. The best ratio of air to fuel for gas engines is 14.7:1. A choke is a device that increases the air/fuel mixture ratio to 15.5: 1 or higher. The choke can be a simple device, such as a valve, or it can have a more complex design.
In the latter case, the choke may be connected directly to the cylinder head or to a fuel injector. Mechanical chokes are designed to increase the amount of fuel injected into the combustion chamber. Electronic choke devices are used to enhance the efficiency of the engine by increasing the number of spark plugs that are ignited by the spark plug wires. Both types have advantages and disadvantages, depending on the application.
For example, a mechanical choke has the advantage of being easy to install and remove. However, it is more difficult to adjust the ignition timing. Also, electronic choke systems are more expensive than mechanical systems, and they are not as reliable as mechanical ones. On the other hand, they have the disadvantage of not being able to control the timing of ignition.
What are the 5 positions of the ignition?
The four positions of the switch are lock, accessory, on, and start. Only use this position if you want to start the engine. When you let go of the pedal, the switch comes back to the ON position. If you have a manual transmission, you can use this switch to switch the transmission from automatic to manual. To do this, turn the ignition on and off, and then press and hold the switch for a few seconds.
When you release it, the automatic transmission will shift into manual mode. You can also use it to change the gear ratio. For example, if you want to go from 3rd to 4th in a 4-speed automatic, press the shift button on the steering wheel. If you press it again, it will return to automatic mode and you will be able to drive the car normally.
How does the igniter work?
When the button on a piezo electric ignitor is pressed, a spring loaded hammer strikes quartz in order to create a spark. This is the process used in lighters. The necessary amount of voltage is created by this. Piezoelectric devices are more durable than devices that rely on an electrical current.
