Can you see above the weeds?

Most problems with gasoline powered rotary lawn mowers as well as other small engines have simple and inexpensive solutions. For example:

This document addresses some of the most common ailments and provides detailed instructions for their diagnosis and cure. In addition, it provides detailed maintenance guidelines to prolong the life and happiness of your lawn mower(s) and other yard equipment.

For electric lawn mower and other electric yard tool problems, refer to the document: Notes on the Troubleshooting and Repair of Small Household Appliances and Power Tools which includes chapters on basic electrical theory (relax, no rocket science) and electric motor testing and repair information.

We will deal with problems the weekend gardener is likely to run into (sometimes, literally!) as well as semi-detailed overhaul instructions. One or more of the books listed in the section: References can be used to supplement this document and can provide much more detailed troubleshooting and repair procedures.

Even if you don't know the difference between a carburetor and a crankshaft, you may still be able to do some of your own work. (Hint: if you drop one of these on your foot, the crankshaft will hurt a lot more!) We begin with an introduction to small engine technology and have more-or-less separate chapters on basic maintenance, intermediate troubleshooting and repairs, and more extensive overhaul procedures.

I welcome comments, additions, hints, corrections, funny or other stories, etc. As the title implies, it is oriented toward the gasoline engine powered rotary lawn mower. However, much of the general information applies to a wide range of yard and shop equipment powered by small 2 and 4 stroke gasoline engines.
