My 9N seems to be running a little slow. A mechanic friend said he thought it sounded like it might be missing. He suggested that I alternately push the spark plug wires off while it was running to see if there was one that did not make a difference. I did that, and the one at the front did not seem to cause it to slow down. However, I checked for spark and it looked ok to me. Does this mean I have bigger problems in the cylinder? Or might the spark look ok but not really be good?
I ordered some new plugs to try, but although I ordered Autolite 437, I got Autolite 3922 with a sticker that said Autolite 437. Are they the same, or is the sticker mistaken?
Thanks
