We need a serviceable big bar saw to do some big cuts, seems like everything modern and ready to go is $5-700, and we'd like to use what we have because we are poorish. Have a Mac 380 that runs if you gas can prime it. Seems to run and cut well when it starts, doesn't always like to start. Found a carb kit thanks to an old thread here https://www.sugarcreeksupply.net/co...ducts/mcculloch-mac-9-flatback-carburetor-kit and also electronic ignition kits. Have a Pro Mac 610 that we've been using with a 32" full chisel full comp 3/8 B&C, it barely turns it over in big wood. The mount pattern seems to match. While the bar mounts seem to match up, didn't get time to try it out on the 380 yet to see if the oiler passages were copasetic. First off, need to get a clutch drum/sprocket for 3/8ths chain, and second, there are 7 and 8 pin rims available. I'm tempted to go for the 8 pin to make use of the torque to turn it into speed, but 87cc is still not enough according to some for power on a bar that big with a modern saw even. http://www.lilredbarn.net/McCulloch-380-Chainsaw-Parts-s/1773.htm Lastly is this gamut even worth my time?
