Will someone check this out and let me know whats going on. For no reason that I can see I just got 6 deg knock. This was at 28% throttle, and it was just for a second then nothing else.
I also have the WOT leaned out to about 12.8-13.1 with no knock. Do you guys think I should play with adding more timeing or lean it out more, or leave it alone?
Last but not least, my W/B AFR is between 15-19 in the 15kpa area. Any idea why and how bad is this?
Thanks for any help/suggestions
