From personal experience and what I have read about here, you will need to replace the bar & chain - they provide safety chain only (liabilty reasons), and the bar has probably been abused.
That said, I just bought one and beyond that issue my chain oiler is non-functional. I am in the process of tear-down so not sure what the issue is but a replacement oiler assy (if needed) can be had for $45.
Buy one of these as a project saw and you will not be disappointed since you know going in that you will be working on it to improve it. I am going through mine from the ground up with intent to install the 84cc kit. Mine was tuned rich, virtually no scarring on the piston, cold compression at 180 and it starts 2nd or 3rd pull (including the first tug with choke on).
I guess I got lucky,,, Mine is a little nicked up but the bar is in great shape, rails were tight, had to swap out the safety chain for some LGX!!!! the ony thing I really need to fix is it leaks bar oil and makes a big mess,, I just lay it on the starter recoil when not in use and no more leaks!!!LOLOL I seem to remember I saw there was an upgrade for the oiler tube to fix it have had it going on 4 years and all Ive done is run the pizz,,, out of it,,, I bought it intending to upgrade to 84CC just havent done it yet!!!!
