1975 351W with 2 bbl carb, runs great for about 10 minutes, then dies.


Chances are it is the ignition box on the fender. It controls the ground signal to the coil and the timing.
If you can duplicate the problem and get it to "not start" you could test the box. Otherwise it may be tough to troubleshoot.
There's a chance something is going on with the pickup coil in the distributor too.

1979 FoMoCo 4 Barrel carb. Getting good fuel flow and pressure to the carb. Engine will start and run for a few seconds then run out of fuel. New fuel pump has been installed. Can blow through gas...


is the needle opeoning on the float in the carb? The fuel bowl should be about half full all the time. As fuel pressure flows into the needle & seat, it fills the fuel bowl until the float pushes the needle into the eat. Sometimes the rubber tipped needle can stick in the seat.

Holley carb? Autolite carb? Holley 4160?

The 1986 Ranger V-6 was a 2.8L 170.4 cu or 2792 cc.
The carb for this engine was a 2 BBL Model 2150, E37E-AEA (Will not cross except for re-build kits!)
The Holley remanufactured PN is 645544

I have a 1984-85 holley 4 barrel and it has


Electric fuel pump most likely has too much pressure for the carb. AFAIK, the Holley 4150/60 & 4165/75 should each demand the usual 4.7-5.3 PSI (4.7 @ idle, 5.3 @ max RPMs), so even the Holley red pump would need some restriction from a regulator. If you want this to be adjusted to its best efficiency, you need to have a fuel pressure gauge installed temporarily, if not on the regulator like I have on my Scout II. FWIW, the regulator I have installed is the Mallory 4307M from CenturyPerformance.com, Summitracing.com, Jegs.com, etc.

http://www.malloryperformance.com/pdf/4307M.pdf

A bad Needle & Seat will do this also, or debris stuck between the Needle and the Seat. This is where light tapping on the bowl helps, but it's best to run the fuel out of the bowl a few times and then the volume flow, or quick filling of the bowl, should loosen up the debris.

You also could have set he fuel float too high. What model carb, the ones I mentioned above (AKA Holley Modular Carbs)? If so, then Holley's site has a tech center & instructions on setting the float(s). www.holley.com

Set the floats carefully and slowly/gradually. Make sure the lock screw is always loose enough before turning the adjustment nut. If you strip out the bowl's threads on an older carb, you'll beat hell finding a replacement. 1/12 turn = 1/32" of fuel height IIRC. You set the fuel level, with pump running (wrap a rag around the carb so gas doesn't leak onto the manifold!!!) so the fuel is just starting to dip out of the "peep-hole" in the side of the float. Removal of the peep/seep-hole screw/plug is necessary first. Clockwise rotation of the nut lowers fuel level IIRC and counter raises fuel level. Again, please check their website. Most people get discouraged when dealing with the Holley Modular Carbs, but they are the simplest and the best carbs on the market. Even if 30+ years old.

Should I rebuild my Ford Bronco 351 Windsor Holly 4 bbl carb or replace it with an Edelbrock carb?


In all my experience, if you know how to correctly tune a edelbrock then go with that, but, holley has outstanding carbs that can muster up to an output of 1,200hp. it would be much cheaper to et a rebuild kit from say, o'reillys, 20-45 dollars depending on which one you have.

Strong order of gas fumes and black residue on spark plugs


The jets in the carb are too big for a 302 with a stock cam. Take it to a carb shop and have them replace the jets with stock jets. (Or DIY and hope). Whne you converted from FI to carb did you replace fuel pump to get correct 7 1/2 psi pressure at carb inlet? FI pumps put out 50+ psi and a regulator maintians pressure at the injectors on the order of 35 psi.. Of course, that much pressure would force inlet needle valve out of it's seat and would probably flood carb totally, but, check the fuel pressure at the carb just to be sure. Good luck. 302's rule!!!!
PS - Check cam specs - FI engine has different cam - intake duration is longer if I remember correctly. Been a while since I got inside an engine...
