Help, Carbon fouled Plugs After setting timeing.

[DakotaMarchildon]

I have a 1993 mx3 1.8 v6. i have had to clean the spark plugs 3 times within 2 months because of carbon fouling. It has always ideled at 1100rpm whith the throttle screw all the way in i dont know why?. I adjusted the timeing to 10 degrees, and after that the spark plugs become fouled within 3 days. Anyone else have this problem or know what it might be?

Pics?

Looks like this?


Would be WAY too rich of your fouling that quick

Check VAF and 02 sensors. Coolant sensor maybe, but not for that rich. No codes?
