i have a 49 cc engine, and am trying to change the spark plug, my problem is i can't seem to get the right socket, my 16mm is too small, and my 21mm is too large (but by a hair) is there any sockets between those 2 that is made for spark plugs? and what size do you think it would be? i'm figuring anything between maybe 18mm to at most 20mm since my 21 is too big. Thanks for all your help.
