I think I will say YES!! If you are in the 9:1 range of rich (which is possible since FJO only goes to 10:1 max rich) then you will have the possibility to detonate/misfire from having too much static compression caused by too much fuel in the cylinder.

I would definitly lean things out a bit until you get to AT LEAST 10.5:1 range and go from there.
