Proper Way to Troubleshoot

What's the best way to learn how to troubleshoot an engine and not be just a parts changer? I hate to change one part and it be something totally different.

First is to properly identify the equipment you intend to troubleshoot...aquire ne and all publications, manuals, etc. Most if not all will usually include at least a brief troubleshooting table for the most common problems.

In all of the manuals that I have there is a "Decision Logic Tree." This will help to guide you through the process with your specific machine.

This is invaluable when you do not know the operation of a machine.

Outside of that there are many techniques for troubleshooting.
Most of them require that you have an understanding of the normal operation, and then apply the scientific method - Formulate a hypothesis ( why isn't this machine <fill in the problem>, and then develop a way to test that hypothesis. Remember, each test will prove or disprove your theory. In either case, the best you can hope for is to learn a little more about the problem, then repeat.

Good luck!

There are three main things that must be present: (1) Compression (2) Carburetion (fuel supply) and (3) a correctly timed spark.
