Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
Can you provide the brand of the mower as well as the brand of the engine so that I can better assist you?
From what I have found just doing a quick search this appears to be a Lawnboy mower with a Kohler engine.
It requires a 13/16" plug wrench and the plug is set at .030" gap.
Thank you it has been a pleasure to assist you.
