Did you have a bar size you are looking for? 16", 18"?
Here are some options:
8ten - Chainsaw Bar & Chain Kit 18 Inch For Stihl Homelite MK1002902
Archer - 18" Guide bar & chain COMBO .325-063-68DL 025 MS210 MS250 replaces Stihl 183SLBA074
Though, like stated above, you will probably get better results and more options especially from Stihl by going with their .050 .325 chain. A couple of years ago they started moving away from .325 .063 to .050 due to its faster cutting (less metal dragging in the wood). And like
@huskihl stated, go with the yellow chain and you should be golden. There are other brands out there that do sell .325 full skip chain if you are looking to eeek out more speed. I think its funny that 3/8 .050 or .058 is pretty much standard and then the .325 went with .063. .063 is better suited for bigger chain like .404.
