Hi Folks -
I am not a carb genius, but I know some of you folks out there are, so I am posting for some help.
I have a 1979 Ford F-150 with a 302. It originally had a Motorcraft 2150 2-V carb which I have replaced as it had never been changed since it was new and it was acting up a bit. I installed a rebuilt one of the same model.
It has ran OK for about a month, with some occaisional hesitation or bogging out at full pedal - I figured it was minor adjustment or a vaccuum problem.
Yesterday, it stalled out completely on me, and now I can't keep it running - so I checked things over today and discovered the problem - it is getting TOO much fuel.
The two round hollow piller post things (sorry, I am not sure what to call them) that come up on each side of the carb, in front of the choke, are FILLING up with fuel and it is being dumped into the carb causing it to FLOOD and thereby stalling the motor.
I thought it might be a stuck float, so I took the top of the carb and had a look. It appeared to be OK - I say 'appeared' cause I am not an expert.
So are there any ideas on what my problem could be?
I suspect:
1) Improperly adjusted Float
2) Malfunctioning Float
3) Wrong Float
4) Something wrong with the Fuel Bowl Vent Valve?
5) Vaccuum issue?

ANY and ALL help is greatly appreciated as right now I am walking as my truck is going no where fast.
Thanks!
Alex

 

A big thanks goes out to Torque1st for all his help.
I got the problem fixed!
The plastic float was fine - though I made a minor adjustment to it.
The needle valve was fine, but the seat had some debris in it - likely junk from the old fuel line since I have a new tank. So it looks like I will be putting in some new fuel line.
Cheers!

 

And a new fuel filter perhaps?

 

New fuel filter - definately.
How often should one change a fuel filter? I change mine with every oil change.

 

If there isn't a lot of crud in the fuel system, once a year should be sufficient.

 

Question on Fuel Line -
What does anybody out there recommend? I know copper tubing is the standard, but is there anything better?

 

Steel tubing is usually preferred over copper, I use 3/8" brake line.

 

Flush it out after replacing things. Any crud that's dislodged will head right back to the inlet seat.

 

LxMan1 - thanks for the input on the fuel filter.

Ford_Six - thanks for the input on the fuel line.

beartracks - thanks for the tip on flushing things out.

 

I have what looks like a Model 2150 2-V carburetor. There is a label on it that says F-2685 on it. I have looked for 3 days on google. What does F-2685 mean when put on a label on the carb????
