Troubleshooting Guide for
Gasoline Engines
Generally speaking, there are very few things that will keep
today’s modern engines from starting. Use good quality
“fresh” fuel and make sure good plugs are installed. Should
the engine fail to start after these items are verified, refer to
the charts on the following page.
In the event that none of the above procedures result
in the engine running properly, contact our service
department for suggestions at:
