I have had this trimmer about 4 years,it was bought new.It has only been used about 10 easy hours.It needs the pull rope reattached and I cant figure out how to get the motor out of the plastic housing,it is the kind with a clutch and a 31cc engine.I have removed every screw and the motor will move away from the housing until the clutch housing stops it.Does anyone what else needs to be done to remove the engine from the housing? The clutch or something has to be removed to get the motor out.The rope cant be replaced until the motor is removed.Thanks for any help guys.
