Hello guys its a long time ago i was bussy.
Now my engine runs great pulling like a fighter yet..
I have install a wideband afr meter set the base timing on 14 btdc .
Set the impco 425 seperately 15.5 afr but if i open the 2 425 together the afr go to 12.5 ad idle, how is this posibble.
Ps the afr fluctuating about 0.7 is this normal i have not a steady number.
Gr Danny thanks for help
