Where are the Spark plugs in a OHV engine and what tool do you use to take metal cover off access Plugs?

In an overhead valve (OHV) engine, the spark plugs are usually located on the top of the cylinder head. Each spark plug is inserted into a threaded hole in the cylinder head and is surrounded by a metal cover called the spark plug boot or ignition coil.

To access the spark plugs in an OHV engine, you will need a spark plug wrench. A spark plug wrench is a specialized wrench with a long, thin shaft that allows it to reach the spark plugs. The wrench has a hex-shaped head that fits over the spark plug, making it easy to turn the plug and remove it from the engine.

To replace the spark plugs in an OHV engine, follow these steps:

1. Pull out ignition coil connected to the spark plug.

2. Use the spark plug wrench to turn the old spark plug counterclockwise until it is removed from the cylinder head.

3. Screw the new spark plug into the cylinder head by turning it clockwise with the spark plug wrench. Be careful not to over-tighten the spark plug as this can damage the threads in the cylinder head.

4. Reconnect the ignition coil.

It's important to check and replace the spark plugs in an OHV engine at the intervals recommended by the manufacturer. Worn spark plugs can cause the engine to run rough, idle poorly, and lose power. Replacing the spark plugs at regular intervals can help to keep the engine running smoothly and efficiently.
