Champion spark plugs have a bad problem of just "suddenly stopped sparking". I have a 2 cylinder briggs that will foul out a plug like your briggs. Never the same cylinder
. I was lucky to get 15 hours out of a plug
. I change to Autolite plugs and never had problems again
. I owned this motor since it was new. I switch to Autolite plugs in all my amall motors. I have 15 small motors. My Son mows 10 yards. they do get used.
