Craftsman 3.7 61cc (358.356091) that is the same thing as a poulan 3800. Comes with the original 20" bar, a 20" power match bar barely used, 6 Oregon LGX full comp chains, and 2 Oregon JGX skip-tooth chains. Skip chains are barely used, the 6 lgx are used but not very much at all. At least 3/4 left on each chain. Muffler is opened a little. Powerful work saw, pretty clean too. $300 + shipping.
