·I replaced my spark plugs recently. The 225 had Autolite 65 plugs, but I got Champion RJ12YC plugs from Checker. When I compared the two, the 65s were about 1/2" longer on the electrode end. The Champions seem to work fine, but I was wondering what difference the shorter length will make. I have seen both listed in various posts here as acceptable for the 225.
