MS461 CFB style

[Canadian farm boy]

Got this saw for a good buddy of mine. It had taken a whack from a tree and appeared to have lots of hours on it so a full rebuild was in order plus since I can’t leave anything stock it also received a port job. I didn’t think to take any before pictures. New crank bearings and gasket set FW side bearing and crank into set the bearing depth of the pto bearing the oil pump is mounted to the case to act as a depth stop.

Very cool build. Excited to see finished videos. Maybe run it against one of your hybrids?

Gotta get rid of the carb limiters. This is the tool for the job. It has LH threads on the end and simply screws into the plastic limiters and you can pull them out.

Stock high side jet is a wimpy little #58. No way it will feed this thing. I removed the jet and drilled it out to a #70
