Last month, we covered starting issues and the diaphragm gasket is one of the items that can cause starting issues on the flathead Briggs engine. The diaphragm dries out over time due to the dry …

Anatomy of the Animal: The Valve Train

Oil leaks are never a pleasant thing to deal with.

Last month, we explained how to replace the side cover gasket. This month, we want to expand on that and explain how to replace a leaking PTO seal, and stop leaks at the valve chamber. Before starting an oil seal leak, take note of which seal you need. There are two seals for the raPTOr …
