The mission of this Web-site has always been to provide parts and technical support for Gilson Snowblowers. My efforts have been focused on the Gilson built snowblower more than the engine. While your engine is supported by an entire industry with many thousands of qualified service outlets the Gilson Snowblower Shop is providing machine support believed to be unique. Even though engines have not been the focus of this hobby, engine information inevitably has crept into the site. This information is scattered throughout this site as it has fit in with telling the story in various ways. This page serves as an index to this engine information.

If you cannot find what you need here the Internet has become a treasure trove of information. YouTube videos will show you how to perform many common repairs. A quick search with Google or another search engine can lead to explanations and forums where you can read responses and ask questions of your own. I encourage you to make use of these resources. The Briggs and Stratton manuals are excellent references for the most common engines. When asked I will do my best to answer to questions but time does not allow me to teach small engine repair by e-mail. The essentials of compression, fuel and ignition are as true as ever and are always a good place to start.
