I picked up a 14' Arkansas that has, what I think to be, a 1970 or 71 Sears 3hp tiller. The idle knob is not attached to anything, the carb has a fuel line from the tank, one hose from the carb that is blocked off and a third tube that is not attached to anything. Is there anyone here that can point me in the right direction, finding parts and info is a bit hard. Thanks in advance.
