Help with Fuel/Carb Problem

[Imdok]

Hi folks, I'm have a problem I can't quite figure out and would appreciate any advice you'd be willing to give me. First off, I have a 1982 F-250 with the 4.9 300 Inline 6 motor with single barrel Carter carburator. A while back I noticed it was starting to take a longer starter turn time for my truck to start and then a lot more foot pumping on the accelerator to get it to start. It finally got to the point where it wouldn't start at all if the truck had sat for more than a day without it being started. I'd pour a very small amount of gas (less than a thimble full) into the carb throat and it would start fine and run all day doing errands and shutting it off and restrarting etc. with no problems restarting it (still works this way). It usually would start the next morning but if I didn't use it that day it wouldn't start the next day after that. Somebody said it sounded like the ball check valve in the fuel pump was allowing the fuel to seep back into the fuel tank (don't know if this guy was full of it or not) so I put a new fuel pump on truck. That wasn't the problem (I should have checked the old fuel pump first). I also unscrewed the fuel line where it goes into the carb and made sure that little housing thing(filter?) that screws into the carb, with the fuel line going into it, wasn't plugged by blowing through etc. I'm out of ideas. We rebuilt this carb a couple of years ago and it hasn't gotten that much use and has always ran fine since then (accept for some automatic choke problems we fixed by installing a manual pull choke setup) Like I said earlier, All it takes is a few drops into the carb throat and the truck starts and runs fine all day with multiple restarts and stops. It's a pain to have to open the hood, unscrew the cleaner housing lid and put a few drops into the carb. It will be even worse now that winter is here. Could it be the accelerator pump (do these single barrel Carters even have one?). Any ideas would really really be appreciated. I'm fairly rural in Alaska so I have to do things for myself for the most part. Thanks

I have seen this before.there is a rubber valve that works with the acclerator pump.what's happening is the fuel is leaking out and when you crank it over you have to fill the carb again.a carb rebuild should helpand they are cheap as well.
