Walbro HDA carb question

[AlexP]

Gentlemen,
Could someone please tell me on a Walbro HDA carburetor on my old Poulan 2800 saw which port on the carburetor is the fuel inlet and which is the return? There is a port on top of the carb and another on the side. Also, there are two holes in the gas tank, a smaller one and a larger one. Thru which one does the fuel supply go? The return fuel hose has a little rubber valve on the end also.

I just rebuilt the carb but the hoses were rotted out and I could not tell which went where. Thanks for any advice.

Alex

I have that carb on a 305 and rebuilt one on a 3300 too. Cant remember without going out to look. But here is a breakdown of the carb from acres site. If you have dial up it takes alittle time to load. Hope it helps.

Looking at the breakdown Cut4fun has listed you will see a nipple on the side, this where the fuel line connect to from the tank that has a filter attached to it.

THANK YOU VERY MUCH. I had the fuel lines reversed per the diagrams on the website link. No wonder the saw didn't want to start. That is a great informational website and I have bookmarked it for future reference. This website is also a fantastic resource. Thanks again.
