Yes you need a Walbro HDA-49.
That was a common carb on alot of that series. Seems the 2700,2800,3000,3300,3500,3600 Poulan Pro 305,335,336 and 365 all used that same carb. I'm going from memory so I might have one wrong or missed one.
There are useally a few on ebay at any given time.
Thanks Mark,Ill find one
