Great video , I like the fact that you didn't edit out all the little problems because any one that cuts wood knows your going to have them. I always carry a small screw driver to adjust the carb because you really can't get one dialed in untill you put in the wood.
Is there something wrong with the twin? It was not impressive at all, and then you confirmed what we all saw and heard. Or maybe there is a reason they don't make any twin saws anymore.
