wheres the mix adjust on a nikki?

With it set to 35º it doesn't backfire like it did at 50º ( I meant 50º before not 50%).



It was doing this (going to 0% when revved) initially but when it ran for a while it was doing the opposite (0% at idle, 35% when revved). I will check again tomorrow but I wasn't misreading it thats what it started doing both times (it was fully warmed up).

I don't think the pre-cat piping will be messed up since its 4 months old and my engine doesn't burn any oil and only leaks a drop or two a day (front main seal). The truck only has one cat (under cab) but thats probably a Canadian thing I guess (here only 96 and later vehicles have 2 cats).
