Chainsaw Repair

Also looks like might be parts from two saws. There are what appears to be two jugs in the pictures. No, I am wrong on the right appears to be a jug, in the middle piston and rod, then a bolt on head but I cannot identify what is on the left that appears to be something the cylinder bolts to and in the center appears to be half a crankshaft?

Also in the small boxes there is what looks like two carbs of differing types, the left most one looks to  be some sort of gravity fed concentric float type because of the black plunger on the right. Could actually be some sort of Bing. The other one I have no clue.
