Hey guys! I just got a 335 Pro from a guy in Georgia Sunday before last. It had a hole in the oil tank which I fixed. I want to run a 3/8 chain and I am pretty sure this saw has the original .325 rim sprocket so could anyone tell me where I can find a 7 pin 3/8 rim sprocket for this saw? Also, I want to use an 18" chain with 33RS but if she'll handle a 20" I will get that. And any advise on where to get the bar and chain reasonable or any other advice on this saw would be appreciated. Thanks!!
