WCFB carb problem. Oil pressure ?

[Lyn Smith]

Got a 1956 Carter WCFB on my 55 265 Q/SA.The problem is that coming out of the water as soon as you let off of the throttle the car wants to die.You have to stick it in neutral real quick, and bring up the rpms to keep it from dying.It also will also try to quit running when you pull into your pit space,and let off of the throttle.Going testing tonight and I have a fuel pressure gauge on the car now.Will keep a eye on the pressure.Also the oil pump that came with the pan I used has 80 lbs of pressure at 6500 rpms.That seems high to me.

Is there any black smoke when you try to keep it running? If so, something little in the needle and seat? It doesn't take much.

[Lyn Smith]

No black smoke.Seems more like it is running out of fuel.

[Chad Fergen]

Does it run down the track fine?

[Lyn Smith]

Yes runs fine at WOT.

May be helpful, maybe not (Grumpy said that to me once!), although we run dual WCFBs, we finally wound up at 14.5 lbs fuel pressure, cured a problem like yours and dying at launch FWIW

Have messed with those old carbs forever. We have run both single and dual in s/s so it is way different- but some things to look at is of course float level and binding,also check floats in hot water for leaks. One of the things carb kits show is to check vacuum passage thru body, fuel will slobber on turns or stops. we have always plugged with a piece of wire. We only run 5 1/2 lbs. for fuel pressure.

Randall-looks like we should try 15 lbs.

Way, way back in the day we would cut the gasket out above the float to get a slightly higher float setting. Forrest Shropshire of '56 Chevy Milk Wagon fame put me on to this.

This may or may not be interesting....at Topeka after Grumpy made our tunnel ram, he stopped by our pit, Ron had the carbs laid out on a table adj float levels with a casting that had been cut out....Grumpy picked up a float, & rubbing his chin said we might try cutting floats & brazing them back together making them small thus holding more fuel

As he climbed on his scooter he said “might work, might not”

Anybody try that? We didn’t, although we cobbled two empty Canton fuel cannsters between regulator and ea carb....result was inconclusive although quite ugly

Once he asked why we didn’t run the fuel injection on the 57 instead of the 2 4’s, Ron said it doesn’t flow enough.....”it will when I get done with it”

Many stories even a R rated one at Mickey’s Landing

Quite the guy

I ran dual WCFBs on my '56 many years ago. I ran rear floats in the front as well. They had the "notched" place in the bottoms, used to have needles & seat assemblies made here in Tulsa, Parker Brothers, that had flat "needles", not tapered. They were open, or closed. They made me a set with a .150" orifice. We had no Holley pumps, nor adjustable fuel pressure regulators I knew of. I put a second Stewart Warner fuel pump on it, with them plumbed parallel. Zero gain. Tried them in series, pegged my hand held shop fuel pressure gauge. This was after we had to go Super Stock (they did away with lower Stock classes at one time.) I could not stop flooding that way, but it was faster.
I finally ran separate wires to one fuel pump. Turned it on with a "universal starter button" under my accelerator pedal. Picked my car up. I could not run more than 8 psi with no flossing, with what we had for needle & seats back then. Parker Brothers handled more than anything else I could find. I also used them in customer's early Quadrajets.
