best lawn mower electric start image
Adam M
what is the mechanism that starts the ignition in a lawn mower engine and how does it work. I have one that you pull a cord and it starts.
Answer
There is a magneto which generates a high voltage electric current, when the flywheel turns. As you pull, this current goes to the spark plug. Gas mixed with air in the carburetor has been admitted to the cylinder through the intake valve- the valve closes, the piston travels up to compress the gas/air; At the critical moment the plug fires and voila! spark ignites the mixture and down goes the piston as the mixture burns... As the piston is driven down, the exhaust valve opens and out goes the burn gas/air.

Well, Consumer Reports just did a rating on lawn mowers in their May 2007 issue. It seems that the self-propelled mowers are much more repair prone than push types though they are easier to operate. Lawn Boy is reported as being the most repair prone push mower brand. Here are their best buys for small, level laws (like we have in CA) Cub cadet, craftsman, Black & Decker and Homelite. They seem to like the cub cadet because it is lighter, combines mowing with fine bagging and a premium engine. Among the electric mowers they like the Black & Decker.
The Toro, Craftsman and Yard Machines come with electric starting.
