Replacing spark plug 917370440 Craftsman Mower. My lawn mower doesn't start after winter storage, so I'm trying to replace the spark plug as one of the options (I've already cleaned and replaced the air filter).Maybe a stupid question, but how do I remove the old spark plug from the mower so I can replace it with the new one?lad to help out. im looking at your craftsman mower model number 917370440.make sure too that you replace with the correct spark plug a champion rj2yxle. (gap: .020).you need like a deep spark plug socket. they have the rubber in the middle.
