Inherited a Husqvarna 56cc . Not sure if it is an A56 or L56 . I think the A series came out in 1968 and the L series came out in 1974 . I would like to rebuild it and can't find parts . Not even an air cleaner . I'll try to post some pics . Any help would be appreciated . Pics are the ID tag , inside the pull cord and inside the bar cover . and
