Hi! My name is Matthew Christian from Tampa, Florida and on behalf of Expert Village, I would like to talk to you about the proper use and maintenance of a yard weed eater. Another area to become familiar with on your gas powered yard tool is the spark plug. Since most gas powered yard tools are two cycle or two stroke engine, the spark plugs tend to foul out rather soon as opposed to your typical spark plug found maybe on your lawn mower or car engine. It may become necessary to replace the spark plug from time to time. You may go to start your gas powered yard tool and it won't start. One good place to check would be the spark plug to see if it is fouled and to do so, we simply remove the spark plug boot. This is what carries the electricity to the spark plug that makes the spark. We will remove this boot and then with an appropriate socket wrench that would fit this spark plug, we simply just slide it down over the spark plug and unscrew the spark plug. When replacing the spark plug, it is imperative that you use the same like and kind spark plug. Not all spark plugs are created equal. Make sure using the same one or the one that is recommended by the manufacturer for your machine. Also another area of importance to know is when you screw the spark plug back in, you do want to snug it in snuggly but do not over tighten the spark plug. You are screwing it into a cast aluminum cylinder head. Over tightening could possibly damage or break the cylinder head. So go ahead and screw it down snuggly but not too tight. Once you have the spark plug back in, go ahead and replace the rubber boot. When you press down, you will hear it kind of pop into position. Kind of want to get that popping sound and we are good to go.
