My father in law gave me his Mccollough mac3200. The saw is probably 7 years old, but has barely any hours on it. He used it once and put it away for a while. The next time he went to use it, it wouldn't start. He took it to a shop to fix and and it worked again. He used it one more time and let it sit. He had trouble starting it again, so he ended up giving it to me. I took the carb off and clean it up. The saw fired right up, but I messed up the fuel mixture screws and I can't seem to get them set correctly. When I rev it to cut wood, it has a flat spot that I can't seem to get rid off. The saw works fine other than this, but I'm beginning to see why he gave it to me. I rather not pay a shop to tune it since the saw isn't worth much and I don't really need it as I have a Stihl ms250. Any one know how to set the mixture screws on this saw?
