Singer Pro Finish Cleaning and Timing Fix

My serger started making this clinky noise, I thought something was caught up in it, so I took it apart and found no foreign objects. What I did find was lots of lint, and threads. I cleaned it with q tips, oil it and adjusted the timing on it. Now it sounds brand new. I only paid $200 and I didn't want to spend $150 to repair it. It now runs like brand new.
