Picked up this beauty from a buddy yesterday, along with a running weed eater for $25. I'll sell the weed eater and get my money back. Anyway, started tearing the saw down to see what I had, it was completely full of mud dober nests, but anyway...
I haven't had a lot of opportunity as yet to work on saws this old. Trying to figure out if it is worth fixing, or parting out. I pulled the carb, to get the model number so I could tear it apart and see what condition it was in, and get a kit ordered if I decide to go that route. Under the carb is this...
At first I thought it was just a rubber stand off for the carburetor, but I noticed it sits perfectly under the hole in the diaphragm cover on the carb. My next thought was that it was an impulse line, but I noticed the carb looks to have an impulse port through the intake manifold. I found the parts diagram for the saw and it lists the part as a "rubber bellows". I found a source for the part and it isn't expensive, but looking at it, it may require splitting the case to repair. I don't really have the tools to do that properly, and I'm always worried that I'll just end up creating a leak I can't fix if I try to rig something.
So, what is the purpose of that part, and does it require splitting the case to replace?
