All of this for a carb kit replacement?? 

Well yesterday I stated to Jim I would have to get really bored to tear into this saw to put in a carb kit.

Well today I was waiting on the mail for 1 more switch before I can tear into the monte. So I grabbed this saw and tore it down for a look see.  Yep carb.  Just like normal I didnt have any walbro HDC  carb kits.

So I started going through my carb kits for matche and. I couldnt believe the huge diaphragm in my WG 3120 carb kits was a match for one side.  I had nothing for the check valve side which is clearly bad if you look at pic.

Oh noticed this yesterday, no H side on these? Whats up with that on these older saws.
