94 carb

I've been wading through a box of small carb parts. All 94 type no Stromberg parts. There's a bunch of inlet needles and seats in there. I've noticed there pretty much all different sizes 're the actual hole for the fuel in, some have additional pair of holes in the side of the seat fitting.
I've had a plod through my books and notes here, can't find any info on the size and application. Anybody out there got this info?
Many thanks in advance.

Martin, there are many aftermarket valves, as well as original OEM valves. The important thing in all cases is to match valve and seat, never mismatch. Secondly, do not use any valve that is not metal to metal. Fiber or rubber valves or seats tend to stick open or closed with the fuel avaialble today, and are total garbage.
 
I use both with the 2 extra holes and w/o them,dosen't seem to make any diff.Now the inlet hole does have 2 diff sizes a smaller one and a little bigger one. I prefer the smaller one for 41 and older 94's and the bigger hole ones for 42 up. OMO. ken ct. Your right on there Alan.

Ford published Service bulletins to cover identification of the 94 parts. I believe in 46-8 date. Many of the parts have numbers stamped such as 69 on the nozzle bar. If there is no number this is also covered.

NO my reasoning is lower HP of the older ones would mean need less gas,OMO for what its worth,and ive mixed them up and doesn't seem to make any diff.I don't have any trouble either one is used.?? ken ct.:)

I've got the service bulletins, most all info there except this fuel inlet size.

In my lookings I found that Strombergs used 3 different sizes in production. From what I been able to workout, the hole got smaller through the years. Maybe as an attempt to combat flooding?
The ones I measured, not with jet gauges I hasten to add but just the id bit of vernier calipers so not accurate enough to size properly, but good enough to compare. One size is marked. 082" this measured with the calipers was. .075", the others measured. .090" and. .103" So these could be. .097" and. .110" ish.
Thanks for replies so far, I started writing this about an hour ago.

Ooo! Forgot this bit. On the shelf is a late ECG 1 1/16" of a Y block with the Large circular boosters. I broke the Ford rebuild transfer on the airhorn when it came to me. So should be as per Ford spec, hopefully. This had the smallest (.082" marked) inlet seat and needle. Mentioned this just for reference.
Also in the box and fuel related, was a Carter fuel pump for an 8BA. Not seen one of these before, only AC ones here.

My '52 F3 had a Carter FP on it. Obviously it was a replacement, but as such it didn't last long as it was bypassed in favor of an electric pump.
 
The change in the Stromberg inlet for the 97 is also covered in early service bulletins. I believe the hole was made smaller to aid in fuel economy. If they are not stamped on the body they are identified by the small machined ring near the input, for the smaller size.
