I was recently given a poulan 2000. It will not start. It seems to have good enough compression, it has spark. I'm thinking maybe the carb? I just don't have much experience with them so any help on how to troubleshoot would be great.
It's probably a Walbro WT-20. I doubt you could find new. K10-WAT will be RB kit.
It's also possible to adapt a MS180 carb, which are available for $8, to work on this saw. IIRC, I pulled choke rod out and put nut, bolt, lock washer in. Drilled new throttle rod hole to match old position. Ground down Idle screw for carb box cover clearance.
Well when I put a little mixed in the carb it fired up and then died. I checked out the carb a little further no dirt or dust in it, it definitely has a tired looking gasket though. Also when the carb is removed there is a port with a thin metal fin covering it. What is this fin an what is it's purpose? My Husqvarna didn't have one I don't think...
I can now get it running while choked but when I take the choke off it revs pretty wildly. I had soaked it in seafoam but thoroughly blew it off and dried it after so I don't know if that would cause this or what
