[QUOTE="Geos7812, post: 436198, member: 20534"] I failed emissions for high CO. I have changed plugs, cap, rotor and oil prior. I have changed the O2 sensor since. Next up I was thinking about timing. If timing is off, could that contribute? I am thinking so but just learning. Thanks all, Geoff [/QUOTE]
