Holley 94 accelerator pump helper spring
 

i'd like your opinions regarding a spring that sits in the well of a Holley 94 carb. Not to be confused with the spring that is part of the accelerator pump itself. Some rebuilders use this and some are against it. It can be a conical spring that helps the accelerator pump return to its normal position. Ford does not show this part in their drawings. I know Ken CT. does not advocate its use. Any other opinions?

All I can add to this is that the Ford engineers rarely added anything to their automobiles that was not needed. And, if they did, Henry would have quickly shut them down. As to your last statement? Consider the source.

Tubman x 3....but, ask Charlie NY with a p m. He seems pretty sharp on these carbs.

I've seen that spring below the pump piston in a few carbs. I agree it's not in any parts drawings. If the hole in the throttle lever for the pump link is worn (or the pin on the link is worn) it can cause some slop and the throttle will move slightly before the pump piston goes down. The helper spring can help take up the slop and make the pump react quicker. That's the only advantage I see to the spring. Also it doesn't hurt anything being in there.

Thanks guys for your input! If ford didn't think it was necessary neither do I!

I think you may have mis-understood my comments. Every 94 I have taken apart had that spring in it; therefore it was probably necessary. Sorry, I can see how my response was unclear.

I also use it.

No harm, just don't leave out the check ball retaining clip.

I've had a few 94s and never found a spring under the accelerator pump plunger.
