Question Holley secondary 'check ball'?

On a 3310-2 (4160) secondary diaphragm assembly, the exploded view shows Ref. #111 as a housing check ball.
I pulled the diaphragm housing all apart and don't see the check ball. Do all 4160's have the ball, or is mine missing?
I bought this off a co-worker who had it on his '70 Z.

There's a couple check balls in the rebuild kit, but not one that'll fit in the housing anywhere.

I bought a "geniune Holley" renew kit and it's missing parts. The secondary housing gasket (Ref. #105) is just one of them. They shorted me 2 fuel bowl screw gaskets as well. It only has 6 plastic washers... not 8. And I thought the kit would come with a new secondary diaphragm\spring.... but no.
Go figure.

Re: Holley secondary 'check ball'?

Joe you'll hear guys say not to run the sec check ball but every rebuild book I have says use it. Without it the sec's open too quick and you may find yourself with a bog and switching to heavier diaphram springs. I have also heard it's a safety device that insures when you take your foot out of it the sec close properly.

Re: Holley secondary 'check ball'?

Yeah... there's a couple "tricks" like that one that I've read about. They seem mostly geared towards racing.
A Ferd site said to go right ahead and chop the air horn off as well.

Re: Holley secondary 'check ball'?

I have always removed the secondary diaphram ball, allows faster opening of secondaries, but its real purpose is an anti backfire valve to protect the diaphram from sudden pressure changes.

Another ball is under the accel pump, check valve and another ball under the squirter, check valve.

Another trick for faster sec opening is removing the lead at the end of the tube on pass side of body midway up pointing the rear and drill the hole to the venturi to 0.083" to allow more signal for the diaphram for secondary opening and plug it with a 10-32 setscrew and Loctite.

I type too slow.

Re: Holley secondary 'check ball'?

How are you supposed to change the accel. pump check ball? Pry the bail off? Then how does it go back together? Dimple where the ends of the bail are set in?

Where's the 'squirter' check valve\ball?

*edit* Ah... the "pump discharge needle\ball weight\check ball" ?
I pulled the nozzle and needle, but ball weight and ball don't fall out. Are they stuck in there? I want to get them out before I dunk the body.

Re: Holley secondary 'check ball'?

Shouldn't be a problem dunking the body with balls as they used to be stainless steel.
Probably steel now. Never measured the balls.

Squirter screw should change to a hollow screw, Holley P/N 26-12.
Some Holley's use a rubber check valve for the accel pump.
3310-2 Renew Kit P/N 37-754, Trick Kit 37-921
P/N's from 1989 Holley catalog.

Re: Holley secondary 'check ball'?

Yeah, the kit comes with the red rubber valve, but my bowl uses the ball and bail. I'm not changing the ball because the clearance is well within the specs. I'm leaving well enough alone.
I think I read somewhere about the screw being changed. Unfortunately I'm having a hard time finding this stuff locally. Hard to believe.

3310-2 Renew Kit P/N 37-754 is what I used... too bad they shorted some of the gaskets.

I can measure the ball Doug... gimme a little bit.

Re: Holley secondary 'check ball'?

I can only come up with the squirter discharge needle... no ball weight or check ball. I blew the passage out in both directions and I can still see something brass down inside. The carb cleaner blew through with no restriction at all. Is that normal if the weight and check ball are still in there?
The passage is soaking in cleaner right now... hopefully something will fall out.

I forgot to mention yesterday about the secondary diaphragm passage that the check ball is supposed to be in... on the top side of the housing where the inlet is (the cover gasket has a hole for it also), the hole has a brass "plug". For lack of a better term.
It looks solid but there could be a hole as small as .005 or smaller. Can't tell. There's no way to get that plug out. Is that normal also? Nothing like that is shown in any drawing or parts break-down.
The pics I have seen show that opening on the top of the housing is OPEN with the cover off.

Is the check ball for that down inside further, that's why I can't get it yet? Could it be gunked down in the passage and stuck?

Re: Holley secondary 'check ball'?

Needle is fine. You see the brass seat it fits against.
Yes, there is a hole in the sec brass plug. Ball sits on top. No balls underneath.

once the sec diaphram is together, you can stick a vacuum pump on it and check the action both ways, with & without vacuum.

Re: Holley secondary 'check ball'?

Thanks Everett...
Before I initially disassembled the sec. diaphragm I tested it with the rod... it held just fine.
And I'm a big dummy... (no comments from the peanut gallery!). The brass fitting has a huge hole in it!
I must have been thinking of something else. If the ball sits on top, that would be a blast to try and put back together! Unfortunately they don't give you one in the kit.
Guess I gotta run without it.

DOUG, that accelerator check ball is 3/16"... IF the one in the kit is correct.

The other check ball in the kit must be for the squirter passage, but it must be for a different model carb.
