Never seen an o ring seal, should be 1/8npt

Another thought.
If running vac advance…
At your idle speed, ported vac should be in action. Assure vac advance arm is still connected. I have seen E clip fall off with resulting arm getting disconnected. This could drop your idle speed and make it run badly, could also explain intake pop.
Recheck initial timing

With engine idling, climb on top of engine and look into venturi.
Dripping from boosters?
Top of all four t slots dry?
Shut off engine and open bowl sight plugs.

If any of the above are wet, reset float level or check needle/seat o ring.
O ring is 008 size.

If all seems good, remove carburetor. Keep if level so there is no fuel spillage.
Hold it up and observe bottom.  Any leakage?  Inspect PV signal hole, dry?
You can also draw vac on signal hole, should be dry and there should be no fuel in there at all.
PVs  themselves rarely leak, but metering block gaskets and PV gaskets often do.


Any other symptoms?

Private msg here works well.
Or email me AirFuelSpark78 at gmail

We have a sat wifi since left the states in November.
Currently off the coast of Portugal.

Anyway, Ray contacted me and I’ll get back to carbs when I get home.  Currently looks like mid October before I get back.
Hopefully these long 100+ day trips are almost over, we are trying to get on a 60/60 rotation, but I have to take a military cargo plane to and from work.

Sorry about format.  Cut and Paste from my spreadsheet.
I list the main bodies I've collected as sometimes we can swap parts around with a complete core to use date code, etc.
List doesn't include those that are currently tagged.  Probably have 40 on hand that are reserved, but that isn't a for sure thing sometimes.

I do not have listed the generics and stuff like 4118's etc that I have on hand.
If you see something, lemme know, I'll tag it for you.

I recently picked up 30-40 good cores from an old friend who is retiring.
many were from his time in the 60s that he has had around for a long time.

Anyway, doesn't do any good if they go from one shelf to another.
I am headed to work tomorrow and likely won't be able to start work on these for 6months to a year due to current workload, but I like to give people the chance to reserve the carbs.
Since I have one day left, I'll work on an inventory to help folks find what they are looking for, I'll post it later as a reply.


Prices given are for restored complete units, I do not sell cores.
S7SK-9510-A List 3926 Date 7B1  $1250
S8MS-9510-C List 4234 Date 823 $1200 RESERVED
S2MS-9510-A List 3259-1 Date 612 $2500 RESERVED

To repeat myself, these are not available today.  I never start work on a carb until I have a customer.  I am simply trying to see if anyone wants to reserve a specific carb for their project.  Once I have you on the list I will not sell it to anyone else.  I will contact you prior to starting work.

Thanks!

Drew

Yeah….
So I remember seeing a thread awhile back about finding original slotted vacuum advance plugs.
I have never had enough of them on hand to sell and barely enough to meet my own need.
The reproduction ones never looked right, too flat etc.

So I did the logical thing and had a cnc mill make a thousand.

If you want one, I’ll be plating them tomorrow. $12 for each, can do better if you want to buy 10 or 100.

Pics:
-original installed
-Left to right, original, reproduction, the ones I had made
-ready to plate

Duncan, the picture you took inside air cleaner ring is just a casting number,
You need to take a pic of the choke horn where list number and date code is.
This will help a buyer

Good luck!

1965 GT350/R-Model / Re: Holley 715 CFM #3259 float level adjustment
« on: June 17, 2021, 09:18:00 AM »
My way of tuning secondary spring is to use a quick change pot.
Find the bog, and scale to heavier until desired results occur.
Once found reinstall original housing with appropriate spring.

The charts are ok ish. Like many such charts it would be hard to take all factors in account....
Especially that there is a bleed hole from the primary signal hole to the secondary.
This is not the same size on all carbs. On old holley spec sheets the bleed hole was noted.

No, secondary ifr was .031 on all of them.

.033 shouldn’t be overly rich, or it should be within range to correct with mixture screws.
The only reason I can see running larger would be due to a radical camshaft. As the camshaft duration or intake plenum becomes larger, more fuel is required.

Example:
If I take a cobrajet carb with it’s typical .076 idle air bleed, and .029 ifr and put it on my truck engine (20in vac at idle, stockish cam, small edelbrock intake), it will run flawlessly as is with mixture screws out 1 turn.
If I take the same carb and put it on my Galaxie (250@.050 cam and massive Tunnelwedge intake), it will barely run with the mixture screws 2.5 turns out.  I would have to alter the idle feed.  I could drill ifr to .035, or could reduce idle air bleed and increase ifr to something like .067/.033

Fairly drastic changes.

The original 3259 had a .031 ifr, I consider this a touch too small. Early 3259-1 had a .033 ifr which is perfect.
Later 3259-1 and reproduction ones (as well as 4118) have a .040 which is massive. Reduce to .033

I do this regularly and am lauded as some carb genius...  (I am not, it’s physics).
.033 ifr and .070 idle air bleed is appropriate for 90% of all cars with a 1 5/16, 1 3/8 venturi, 1 11/16 throttle bore carb.
Very rarely does an engine require being outside of this range.
