[QUOTE="AUSSIE1, post: 2258891, member: 11266"] Yeah I understand the discussion Niko. Where is the carb getting it's fuel from at half throttle? All circuits. The circuits are adjusted by mixture screws. Carbs with the exception of the early saws (as someone stated) have a multi stage idle/low circuit that works through the throttle range. The saw is feeding of the main at half throttle, not just at WOT. The amount needed is determined by engine demand/atmospheric pressure. Hence I don't see the issue at half throttle. [/QUOTE]
