How to check the spark plug gap on a Yamaha Generator

Checking the spark plug gap on a Yamaha generator is an important part of regular maintenance. Here are the steps to follow

Determine the type of spark plug your generator uses. You can find this information in the owner’s manual or by consulting a Yamaha consumer generator dealer.
Use a spark plug gap tool to measure the gap between the electrodes on the spark plug. The gap should be set to the manufacturer’s recommended size, which can also be found in your owner’s manual or from a Yamaha consumer generator dealer.
If necessary, adjust the gap with a feeler gauge and then re-check it with your spark plug gap tool to make sure it is correct.
Once you have confirmed that the gap is set correctly, reinstall your spark plug into your generator, and you are ready to go.

How to adjust the spark plug gap on a Yamaha Generator

Adjusting the spark plug gap on a Yamaha Generator is a relatively simple process. Here are the steps to follow

Locate the spark plug on your generator and remove it from the engine. Mostly, the spark plug is located on the upper side of the engine.
Measure the gap between the two electrodes of the spark plug using a feeler gauge or wire thickness gauge.
If necessary, adjust the gap by bending one of the electrodes with a pair of pliers until it reaches the desired size.
Re-install the spark plug into your generator and tighten it securely with a wrench or socket set.
Start up your generator and check that it is running properly before use.
