I was at my local saw shop, found a poulan 306a in good condition. was able to by it for the repair bill owed . put a 20 inch bar 3/8-50 chain on it. Ran it from 8:00 am till 4:00 pm the next day. no problems . I will say I paid less than 100 bucks for the whole setup. Dosen't feed through as fast as my son in laws 390 but did a good job. ( I removed 3 dyeing hickorys old trees.) Any one know what cc this saw is.
