Choosing a used chain saw

[Project man]

Hello, I'm in the market for a larger saw. Currently I have a rancher 450 which is good but I am looking for a stronger larger model for falling some oak and maple trees 18-24" in diameter. I want to take a look at 2 saws in my vicinity. There is a MS 361 and a MS 391 both available for @ the same cost. Obviously, the condition of the saw will be a big factor in this purchase. Is there any comments whether one is better than the other or if one is easier to use or is easier to service than the other? When I go to check out the saws, I wanted to bring a compression gauge to make sure the compression is good and was wondering what a good compression reading would be on saws of these displacements......thanks again for any comments and ideas!!

I would not bother with the 391 and concentrate on the 361- much better made saw.
If it falls down the rope, leave it, if it slow chugs- take it.
Better to take a T27 wrench and look at the piston through the exhaust port than rely on compression testing.

As Bob said......361
