Post a pic of the right side of the engine also. If it's '73 ish and older it should have a tag about the size of a credit cart attached by 2 rivets to the front of the pull start cover/blower housing. If it's '74 ish and newer it should be stamped on top of the blower housing/pull start cover. Post both the model & serial # (it will be stamped) from either one of those 2 places to better determine the year and hp rating etc.
