I'm posting my review about my new purchase yesterday. First things first, its much lighter than my FS130R which was its selling point. I filled it up today with fresh 93 octane mixed with the standared Stihl oiul mix. It fired up on the 5th pull out of the box. It tachs up fast and has good tone to it, that is one good thing about the new 4mix engines they aren't as loud as the older 2 strokes. As of right now the only thing I can fault it for is the balance of weight is off with the engine being much heavier even when the D-handle is slid all the way to the top. It seems all the weight came out of the shaft and gear box on this model. I will post as I get a chance to run it more over the next feww months.
