The 5-piece cooling air duct encloses the area of the mechanics where the engine sits, so that the cooling air delivered does not deviate from its path to the cylinder head. Since the opening for the carburettor linkage differs depending on the engine used, cut it out yourself. Keep the cut-out as small as possible. When bolting the duct parts together, avoid stress and insert the enclosed rubber U-washers (Ord.No. 90555) between the duct and the lens-head flange screw (Ord.No. 90410). Only tighten the screws lightly!
