Craftsman Model 917.387242 Lawnmower

Posted by Loraki WA (My Page) on

I'm a senior citizen and am mechanically challenged. I am trying to find the air filter on my lawnmower. I've removed screws looking for it, but the stupid owner's manual doesn't show a picture of where it's located or tell you anywhere!

Also, I figured out how to change the spark plug, but don't know how to set the gap at .030 inch.

Hope someone can/will help me.

The air filter is in a black plastic canister that is roughly 2 inches in diameter and 4 inches long. Turn it slightly counter clockwise and pull the plastic cover ahead, pry out the filter and replace it with the new canister. It is straight ahead from the carburetor, which is just ahead of the muffler. I wouldn't really worry about the plug gap if it is a big deal. You need to purchase a spark plug gauge to do so.
