I'm wondering if anyone has installed a genuine 090 piston, cylinder, crank, and bearing into an after market case such as the huztl? I have an opportunity to purchase a VERY well used (think sawed hard and put up wet) 090 that is scarred and broken but reported to run and function as it should. I intend to use the saw in a mill but I would like to replace the broken clutch cover as well as the case. To me it looks as if the chain has taken a big bite out of the case. Looking for guidance and or experience with this kind of repair. I am also trying to avoid a money pit as the saw is at the top of what I want to pay considering condition. Thanks for any assistance.
