ok.thats valuable info. Has anyone done adjustments to their eha valve and measured their AFR afterwards using an open loop system? My car doesnt have o2 sensor.im trying 2 get an idea of how much adjustment wil yield what result. Ie 1/4 turn enriches and makes the mixture 14 at idle, 12 at part throttle and 10 at WOT and 1/2 turn makes it 14,11 and 8.
I wouldnt want 2 do the adjustment myself.sounds like a hectic job.just want 2 knw what 2 tell my merc mech 2 do.
