The tube that begins with the tank pickup filter is the one that carries fuel from the tank to the carburetor. That one needs to connect to the carburetor's fuel intake. Try pumping the primer and seeing which carburetor connection sucks when you do it. That should be the one to connect to the pickup filter.
I may have it right now. The one that is connected through to the pickup filter in the tank is on the left brass pipe (in my attachment) just under the primer bulb. I started the machine. Also i must mention that the carby has now a new kit, plug, air filter and pickup filter. Hope it keeps going. Thanks for your help.
