lost

[lil red yarder]

I am working on a 76 f150 with a 390cid 2bbl C6 auto 203 t-case. i don't know fords at all, they are not my thing. the problem im having is that i can get it to start and idle but when you give it gas it dies. my thought was the fuel filter (after removing the air cleaner). I did a tune up and still the same. Granted i cant find the fuel filter. i was told it should be screwed into the carberator and not on the frame rail, its not there. I am lost on what it could be unless the carb need rebuilt. i am looking for anything that mite be the problem.

I thought this thread might be about the TV show.

How long has the engine sat without being run ?

Check the vaccum advance for being seized or diaphram torn.
Do you have a timing light ?
Hook it up and check it for advancing when you try to rev it up.

Get back with answers

Initial thought is a float problem. As for the filter, if it's a stock carb, it should be screwed in at the bottom left as you're looking at the carb. If not, someone may have put an inline filter in between the fuel pump and carb. Also possible they put one in somewhere between the tank and the fuel pump, so follow that fuel line. If it's not there, then that could be causing you at least part of your problems.

That being said, if it'll run and idle, I say your float is stuck and either flooding out the truck or depriving it of fuel. Any idea where your idle is set at?

See if there is a cannister attached to the bottom of the fuel pump.There is a filter element in that can,and it is a service part.Check the entire fuel line to the tank as there might be other inline filters present.How fresh is the fuel in it?As others have suggested here,check your idle,base timing,and float level.

The carb inlet IS a filter, although at first glance you may not think so. Unscrew it, and look inside. You will see it is not straight through, but has micro holes around the perimeter inside. These can and DO clog, and have been host to many a mysterious engine dying.

Good call. I didn't even think about that. Never actually seen one either.

True...but it is easily replaced by a nipple fitting.

That just sounds SOOOO wrong

I'm not sure exactly how long it has sat for. I wanna say it sat for about 2 years but it could be longer. ill go ahead and just rebuild the carb

Id drain that gas out and put some new stuff in there.

Agreed...skunky gas wouldn't help the situation either. However, I've poured some Stabil in vehicles that have sat much longer than 2 years, let the Stabil do it's thing and with some coaxing the vehicle would at least run down the road.

i drained the gas before i did anything else

When it dies do you get a strong smell of gas?
