Bearings and Bushings

In previous blog posts we've talked about maintenance of your lawnmower by changing filters, plugs and keeping blades sharp but we haven't covered how important an oil change is to your engine. It is the key ingredient that keeps everything mechanical inside from grinding to a halt. And nothing is more unforgiving for lack of proper oil changes than bearings and bushings.

Hardware Parts Assortments

There are many times you need a simple cotter pin or E-clip to fix something on your lawnmower. These are very common types of fasteners used on all kinds of power equipment. In fact they are often used on kids peddle toys, bicycles and other yard tools with wheels.

Air Filters

The importance of a clean air filter.


Your lawnmower engine needs air to mix with the gasoline vapor to create the internal explosion that drives the motor. All this is controlled by the carburetor. The amount of gas used is controlled by the throttle valve that you can often manually adjust at the speed controls on the handle. The amount of air used is determine by the internal vacuum caused by the piston moving down in the cylinder. It creates a vacuum that draws in the Air/Fuel Vapor mixture before compressing it for the spark plug to ignite and produce the power stroke that drives the engine. So old gas that doesn't vaporize well or a air filter that is dirty will affect how well the engine can suck in the proper Air/Fuel Vapor. This is why a clean air filter and fresh gas are so important to a clean running engine. You are probably getting fresh gas for your engine as you use it up but are you checking your air filter?

It's midway through the lawn cutting season, and it's probably time to check your spark plug on your lawnmower. It the only source of ignition on a single cylinder lawnmower engine so it's important to make sure its in proper condition.
Below is a spark plug in good shape. Slight gray color and the center electrode is still a solid shape with sharp edges (not rounded off). If your spark plug looks like this then put it back in and keep mowing.
