Help!!!I have an old Homelite XL-123 chainsaw that has been drop dead reliable for about 30 years...It still runs great. The problem is that I need a new clutch for it. Sprockets are not a problem to find but I cant seem to find a clutch. The shoes are the only part of the clutch I need....Anyone know of a good Homelite parts source etc that may be of help?????Thanks in advance....
