Question:
I have a rotary lawn mower 917.384513, product no. 6021P purchased 11/2011. I have 3 different deep well spark plug sockets and none of them fit the plug. What size do I need and where can I get a replacement plug? Seats does not know the answer to either question. It is only 1 year old and I had a bunch of difficulty starting it for the first cut of the 2nd season - over an hour. I think it is the plug, but I can't get the old one out. Thx! Phil
