Try adjusting to co pot to give a better idle ive found cossies like to run in the 13's afr
in an ideal world 14.7 at idle would be great but it never happens like that.
But co pot adjust L8 not go that low (afr 13) because lambda adjust it close to 14.7. Adjust is very minimal ,nothing like L6 normal operation without lambda.
Better ignition maybe cure the problem ,now i have original distributor system with Crane cams fireball LX91 coil and all wires and all are good condition.
Spark gap 0.7mm without high boost problems 1.5bar. I try 0.9mm gap if it not too much in boost.
Chip fueling in idle can be little lean to this engine maybe.
