i have a 2001 bear tracker i bought for my dad for christmas it starts fine but it seems to be a bugger to pull over . revs to high heaven as soon as you start it . and it bogs like crazy when you try to drive it. exhaust is clean, air box is clean, pulled the carb and the needle and seat are gnarled bad..got them ordered .. my question is i hear the carb manifold (the part that goes from the carb to the motor) are bad for leaking air could that be another reason for the hiccup?? and anyone got any idea why the recoil is so hard to pullover?? or have a 2001 beartracker is it hard to pullover??? any help is appreciated...
