I am blogging about lawn mowers at the request of my next door neighbor. Last Saturday morning as I started my early morning walk with the dogs, I noticed my neighbor struggling to start her lawn mower. I am conscious not to patronize as I have a tendency to give too much unsolicited advice when I am only wanting to help, I let her know in passing that there are only 3 things at play when running a lawn mower: air, spark and fuel. I went about my dog walk and upon returning she was still fussing. She said the air filter was clean and she had gas so…. I said, “It’s your spark plug”. I promptly went into my garage for a new plug and …. yep, it started right up. So … remember, trouble starting your lawn mower? 3 things: fuel, spark and air!
