Does a 14 hp Briggs Stratton engine on riding lawn mower have overhead valves?

It's impossible to say for sure whether a 14 hp Briggs & Stratton engine on a riding lawnmower has overhead valves without knowing the specific model number. Briggs & Stratton has produced both overhead valve (OHV) and side valve (SV) engines in the 14 hp range.

Here's how you can find out:

1. Locate the engine model number. It's usually found on a metal tag attached to the engine.

2. Search online for the engine's specifications. Use the model number to find the engine's manual or specifications sheet on Briggs & Stratton's website or other online resources. This will tell you the valve configuration.

Here are some general clues that may suggest an OHV engine:

* Newer engines: Briggs & Stratton transitioned to primarily using OHV engines in recent years.

* Larger displacement: Higher horsepower engines are more likely to be OHV.

* Improved performance: OHV engines are generally known for better fuel efficiency and performance compared to SV engines.

Important Note: While OHV engines offer advantages, they can also be more complex and expensive to repair than SV engines.
