i have a gauge and what should it be reading when ticking over and the same on running lean rich inbetween or nothing

scoobian

at idle you want to be at abut 14.7 (stoichometric optimum)
and then at light loads at almost any revs yu wanna be at or a little richer than 14.7 ...but not t much (good fuel economy)

as load increases (load = acceleration or uphill driving) then the AFR shold get richer to something like a max of 10.5 to 11

probably

no responsibility for any damage incurred as a result of these OPINIONS

max fuel eco 16:1-17:1
good load 11:1- 12.5:1
