Good afternoon all. While poking around "That auction site", I saw several Husky saws for sale. Looked like most of them had the saw case as the crankcase for the engine. [:'(] I'm looking to do a 50cc or so motor for a Midwest Extra and thought these might be a possability. The model numbers I looked at are 2051, 266, 55, and a Jonsered 670. Anyone have any info on these? Are there better Husky engines to use? I have a Poulan 46 (still a saw) but was looking for some more grunt. Thanks in advance for the help.
