Bought this 394 as a project saw last year. Had a bad carbon smear on the piston and cracked flywheel side crank case. It ran good so I cleaned the carbon off the piston and ran it for a year.
Well, the carbon smear returned and looked much worse. Looked like it was starting to transfer, time for a rebuild. Note the polish and port shadow on the exhaust skirt, piston is well worn and long overdue for replacement. This isn’t going to be a PSP shelf queen rebuild, if it’s not broke I’m not fixing it, if it’s ugly I don’t care. This saw is going to work.
Here’s the crack in the case. Saw passed Pressure and Vacuum test, but who likes cracked cases...time to swap it out.
Edit: photos don’t illustrate the order in which I assembled the saw, was waiting on some small parts til late in the day.
