Truck is stalling out...Do I need a new carb?

Sometimes you get lucky and that will pull the junk off the needle and seat. Sometimes you don't.

As mentioned above, the fuel filter is in the front of the carb behind the large fitting. If you look close on the front of the carb under that vacuum line it will say filter. It's a bronze filter and I like to chuck those and replace them with an inline filter (Fram G2 or G3 depending on whether you have a 5/16 or 3/8 fuel line). I put the filter down by the frame rail on the hose coming from the tank.

OlBlue81,
Thanks for the tip. After getting under the truck I see two lines going into the fuel pump. The one closest to the frame is the larger one. It looks as if both of those lines are attached to metal lines going back towards the gas tank. Is that second smaller line a vaccuum line? Thanks so much for your help!
