Carb rebuild
I think my carb could really use a rebuild. The choke doesn't work, and the thr truck just hasn't had any attention in years. I was wondering what options I have: Is there somewhere I can take it and exchange for a rebuilt one? Or do I have to rebuild it myself? If so, how hard of a job is it? My 79 F150 Has the I6 and a 1 barrel carb.
Also, all the vac lines besides the advance and brake booster are plugged, should I try to restore these connections?
Thanks in Advance,
Dan

You can get a rebuild kit at any auto parts store for about $30. The rebuild is simple, even if you've never done one. All you need is a small set of tools, some patience, a clean workspace, and it's a piece of cake.
I rebuilt mine a couple of months ago. I had never been in a carbureator before of any kind. I had it apart and back together in about 2 hours. Worked perfectly the first time.
You will definately want to clean out those vaccuum lines as well - proper vaccuum going to where it's supposed to is critical to getting good performance and mileage out of the engine.

Thanks for the tips!
When I said all the vac lines are plugged (except for the advance and brake booster), I meant they all have gulf tees in them. Is this hurting my mileage/performance? or are these simply due to the fact there are no emissions components on the engine? I would like to improve my mileage as much as I can without major work or spending a lot of money.
Thanks Again

Your 79 had some emissions stuff on it. Two lines to the Distributor, and maybe a fast Idle solenoid controlled by a Vacuam/thermal switch on top the head in the front.
It wont hurt to run it like it is, but it would have been better if your Shade tree engineer had left it like it was.
Get a can of Berrymans and soak your carb parts overnight it the can. You can wash the Berrymans off with hot water.
Then some wires, like Gas welding tip cleaners will help in making sure all the passages in the carb are clean.
Put the new Needle valve and seat that comes with the kit and make sure the float level adjustmaents are right.
That should do it if the carb Venturi is not worn out.
One thing that signal's the end of the Carb is the wear around the throttle valve shaft. I dont know how to fix that, but it will affect the Idle if that shaft let's air it around the shaft itself.
You can get rebuilt carbs from almost any parts house.
