During 20 lap feature Sat night ( I won, under heavy pressure! first ever in Kart racing), felt like my animal started running raggeddy on top end at about lap 18. Batts went bad in tach, so I have no RPM or lap time to verify my feeling. Plug looked good after race( 4 races on it), plenty of fuel nothing overtly or obviously wrong...was this in my head while under pressure, hot motor at 20+ laps, or time to change the plug? What's the lifespan of an Autolight racing plug in an unrestricted animal?
