Try your local Home Depot. I picked up a display demo that had the bar, chain and other small parts missing. The engine was complete and brand new. After speaking with the manager and telling him what I wanted it for he let me have it for $30. - Nice guy huh! I got my conversion kit from ScottBaldridgeConversions.com and am waiting on my CH ignition. I plan on installing it on a GP Wagstaff.
