You guys are too funny. The 620 is strong... 7 pin on it. I made that first video hoping people would see its not rigged... no hidden turbo on the 620 lol well there might as well be its a fun saw... it really it the power curve, not soley torque or hp but the curve as a whole. Let me know if there is any other stuff you guys want to see with the 620 (no chainsaw juggling) lmao.
