I'm getting confussing information about which plugs I should be using. I have a 120 Johnson, model J120TLAEM, serial#02306410. Can anyone tell me exactly what year it is and what the other letters mean. The local dealer gave me Champion QL82YC plugs. Clymers manual gives two different choices. The motor runs good and strong, but I have to clean plugs every other trip or it misses out for the first 10-15 minutes. Most of my running is WOT or 3/4 throttle pulling skiers or running to a fishing hole. Very little time trolling or slow speed. Whats the best plug for my motor and what gap!
