The chainsaw guy shop talk McCulloch Pro Mac 700 chainsaw 2 4 2 

That’s a great saw Michael, Handles a 28 inch with Skip 3/8 very well WestCoastMuscleSaws TheChainSawGuy Rich

@@WestCoastMuscleSaws I put my first couple tanks of fuel through it yesterday. This saw is a real sweetheart and an absolute delight to run. I would love to get a 28 inch bar which would make it easier on the back than the stock 20. Something about that saw does it for me even with having modern Husqvarnas in the stable. A new favorite for sure

You’ll love it with the 28 B/c. A small mount Husqvarna bar will fir with minor modifications. WestCoastMuscleSaws TheChainSawGuy Rich

You need a new roller bearing, I had the same problem on my 10-10s

72cc's. They came with bars up to 32"

Believe it's 70.5 cc actually
