Got the 340 purge lines hooked up and tried out the rescue chain. It was way too grabby. Needs to either be ground back and depth gauges accurately set or just tossed. This chain came on another saw and had a 45 degree cutter angle and about 60 thousandths raker depth. I’ve started to convert it back to 25 degrees but with the raker depth so low it’s not suitable for a 40 cc saw.
Put the new bar and chain on it, cuts better. Did a muffler mod and it cuts better again.
Swiss cheese muff mods may not be pretty but they work and the saw isn’t crackly at all.
340 at zero balance on the tailgate with the old bar and chain. Just barely sitting there.

Cousins. The mm’d 130 will outcut the stock 340

With Swiss cheese treatment the 340 picked up significant torque and throttle response. Now it will outcut the 130.
