I have a Craftsman 32cc WeedWacker with a Walbro WT628 Carb. Please note the following as others I have sought help from evidently don't read it. I have "reeplaced" with new parts: Carb; air and fuel filters; fuel lines; spark plug; gasket. I need specific instructions on the routing of fuel lines. I have gotten about half dozen different directions and I am confused. What port on carb does fuel line go; what port on carb goes to bulb (left or right port on bulb; where does return line attach and then go to tank?
I have tried everything and the unit may start, not always but ALWAYS only runs for 5- 10 seconds and the dies just like it runs out of fuel (which it probably does. But the ? Is Why?) I am about to just rash it even though it is only a year old. Daughter gave it to me last Fathers Day. I, personally wouldn't own anything "Sears". Help!!

Hi,
I doubt Sears will be helpful, I gather it is a remote primer. I has check valves in it. Push the bulb in while holding a finger over one fitting. One of them will not allow it to return (I think it is the short one) and so that is the that pushes the gas through the carb, The one from the fuel filter goes to the other. The fitting near the top of the carb is the entrance and the one near the bottom the exit ( it goes back to the tank.
