This is the third thread I stated as a result of yesterdays excursion.
When I first installed my Innovate wide band system I mentioned here that the readings were very good and some here suggested that I leave the Carb alone which I did.
Yesterday when I left the house I noticed the readings on hard Acceleration were 16 - 18, then in Cruise at about 50-55 the readings were above 15 nearer 16, when I coasted, at first the gauge would read 10-12 then go all the way to 20. The Engine backfired through the Carb once when I floored it to see if the Secondaries would open. It has never done that before. Have not heard any pinging, and other than what I mentioned here the engine runs really smooth.
While sitting in the Feed Store Parking lot yesterday, I removed the nbr 7 Plug while checking for spark. The first thing I noticed was how white the ground and element was.
Any thoughts would be appreciated.
