If you need a repair part from a chainsaw carb diaphragm, to lawnmower motor parts to a palm sander switch, no matter the manufacturer, give ereplacementparts.com a try next time. There are a lot of things I couldn't find, like a McCoullough Timber Bear recoil bolt, but many other times they came through just fine.
One cool thing for example, once you find your part and get the part number, start over again with just the part number search and it will pop up all the machines it fits and you will notice many times different brands cost more than two times the cost of others for the IDENTICAL part. Try it and try to post back and let us know if it worked ok or not. I for one have been very satisfied. That is ereplacementparts.com
