I'm going to sticky this. Thanks for posting. I don't suppose you could scan the mag for better images could you?
Having a wideband O2 sensor air fuel meter their graph doesnt show what a wideband reports. Cold idle 10 to 12 Max power 12 to 13 (and cooling..) ..uphill Idle 14 to 15 (lean best idle) .. driving on the level Light load 15 to 17 .. downhill at 50 And before considering changing your carburettor just consider that the 34pict-3 idle circuit being completely separated means it should provide better management of mixture than a lot of aftermarket solutions where idle is set by cracking open the main throttle. Like a progressive.
..... so I'm on the road to redemption if I'm going to swap a Bocar for a Solex when the de-icing bits go in this winter?
