I did have to up the idle jet to a 60 to get it to 1.3% CO. The idle mixture screw is lead plugged, and I have a superstitous horror of messing with them since I blew up my 2CV that way when I was a student.
However, does someone who knows there onions think I'd be better off dropping the idle jet and fiddling with the screw? or is it a six and two threes?
