McCulloch Pro Mac 650 Carb settings

[jambalini]

Can anyone please tell me what the base carb settings are for a McCulloch Pro Mac 650 please. I know to lightly screw the H and L screws in fully but I don't know how many turns to screw each one out by.

thanks

Andy

Generally a good starting point is a turn and a half. Not positive that would be the recommended starting point for a mac 650.

My handy dandy service manual says it has a Walbro HDB carb. Start at 1 turn from seat and fine tune from that.
