Phil 32DL6 Posted August 31, 2009 Share Posted August 31, 2009 (edited) Very, very timely article! Today I was doing some experiments to narrow down an engine stumbling problem and I wanted to eliminate cylinder detonation issues. So I pulled the plugs and compared them to the pics in the article: everyone was spot-on perfect....even down to the color change at the bend in the ground strap and 1-1/2 dull threads.Didn't solve my problem, cause it's most probably a weakly performing mechanical fuel pump that can't handle much engine loading, but eliminating possibilities is always progress!A big plug for the link!
