Used to be 11.5:1
After changed to Rising rate fuel regulator, dislike the setting.
Change back to old regulator.
Also change setting on boost controller to weaken the boost due to overboost.
But All the sudden, found that when boost 0.6 bar, air fuel more then 18:1.
no leak of fuel at regulator.
No leak of sound of vaccum hose.
fuel gauge from 50 PSI , now changed to 60 PSI, still more then A/F 18:1
I guess nothing else i had done recently beside above mention.
Any other reason cause it?
