new to this forum and also new to the sears custom 7. just bought it with a snow blade and a snow blower. motor was weak in it so i replaced it with a 9 hp troybilt motor with the horizontal shaft. the problem im having is the old motor didnt have a pulley on it for the blower. i have the original belt and the original pulley on the blower but nothing for the motor. outside diameter on the blower pulley is 5 inches and the 1 i put on the motor is 4 1/4" inches(had 1 at the house). it is to tight as it doesnt disinguage from the motor totally when the handle is pushed in. it also doesnt throw the snow more than about a foot. can any 1 please tell me what size pulley goes on the motor for 1 of these old girls? its my belief it isnt spinning fast enough which would mean a bigger pulley on the motor than the blower(blower is already a 5" and is stock). any help would be appreciated as i will go to store and get a new belt and pulley tonight b4 the storm comes in tomorrow. thanks!
