My truck will try and sometimes will stall when I stop hard. Only when I'm stopping hard to avoid nailing the guy in front of me, not the every day driving.
It feels like it's fuel starved.
Edelbrock intake and Holley 4 barrel
Is it the g-force creating a temporary starvation?
Is there a way to correct this?

Most likely it is fuel spilling out of the vent tubes causing temporary flooding. You can solve the problem by placing a proper fitting hose over the 2 vents to connect them together. The hose will be in an arch shape. Cut a small slot in the upper most, outside, of the hose at approximately the center.

JWL
approximately where are these vent on the Holley 1850?

Fibber Mcgee · 10-05-2012, 09:27 AM

The vents are cast into the top of the carb they are the tubes that stick up between the primaries and secondary butterflies.

On the picture you posted...imagine a line drawn right down the center of carb from front to rear. The forwardmost and rearmost holes the line crosses WITHIN the circle that retains the air cleaner are the vent stacks for the two bowls.

Exactly

bugseigel,

The throttle plates may be closing too quickly. My the Ford 4100 (4-bbl) and 2100 (2-bbl) series carbs came with an "anti-stall dashpot" that dampened the throttle plate closure during sudden deceleration/stopping.

I don't see these mounted on cars too much these days but I kept it on mine and have never had a problem. Also, I don't know if it was primarily used with automatic transmissions (which I have) or all types of transmissions.

There's no way to get a hose over #3. Could we possibly insert the proper diameter into each or would that be too restrictive?

If the carb is mounted backward for ease of hooking up the linkage, that may be your problem. ! had a similiar problem on my '35 pick-up. when I turned the carb back around (like Holly designed it to operate), the problem went away.

this one is mounted in the correct orientation.

I don't know anything about these carbs but if the truck is sitting and you race the engine a little and snap your foot off the pedal does it stall then?? G.M.
