Hot Rods Stromberg 97 ??

Hey guys,

anybody can tell from this pictures if this is a 97 ?

http://www.cocheantiguo.com/clasificados/detail.php?siteid=22857&show_still=1

 

Base is 97 type. Size designation on right of carb is too small to see, left side with the big "97" is not shown...ask for a picture of left side.

 

Can't tell. It could be a 48, 81 or 97

 

Markings needed: On left side main body, behind linkage, tiny 31/32" (.97!) mark, on left main body circular boss with "97", fairly large characters.

 

But is the "97" stamp always present on a 97 ? This one has none

Have a read of this......

No, it is not always there. I've had 48s and 97s without a cast number.

 

if their is no stamp at all on the drivers side (left) of the carb, it usually indicates that it is a stromberg 48 carb. it will be marked 1 1/32 on the right side.

 

I think its a 48 but I'm no expert.

 

What currancy is that?

 

Pictures are inadequate to tell...need other side. In my experience, 97's with no cast "97" still have the raised circular boss where it should be. No boss would be a model 40 or 48 carb.

 

Definate NO!!--------Don

 

It's not a 48 because the top and the linkage have the provision for the detent plunger to hold the choke open. 48's had no detent plunger.

 

So ? then its a 40 or a 81 ?

 

Thats Argentine Pesos.
3.7 = 1 dollar

 

The top and base shown were used on 97 and 81...looks like throttle bores are 97 size...but those parts are frequently found on 48's as rebuilders mixed parts. I have several like that.
You can see the tiny circle on R side under linkage where size designation goes...1 1/32 for 40 and 48, 31/32 for 97, but I cannot begin to read it.
Other side of bowl... a "97" or at least a circular boss for 97, either nothing or a SMALL cast 48 for the big carbs. Part number cast somewhere on main body (P******) will also ID...part number for other bits will lead to 97, but actual identity is the bowl casting.

 

It has the following US patent numbers :

1404879
1545821
1645341

Also reads "EE1" on the base

 

EE-1 makes it 97 or 48, if the linkage for the accelerator pump has a summer and winter position, then it is probably a 97

 

Yes, it does have the W and S

 

The base and top are firmly established already as 97 type. Central body ID is needed to tell if 48 or 97...

 

Not always. Some of the replacement Strombergs when they were made in NY have the large embosses circle with no number.

It is certainly a 97 with 31/32 venturi size.

 

This should settle it once and for all. I say it's the rare South American prototype 9super7.

 

Of course, uncle max is correct..Prototype. The $64,000.00 ??????? game..

Hi Banjo, how can you tell ?

 

I would ask the seller to send more pictures...

 

All you need is either a better blowup of right side pic, where size marking is present but not readable now, or a pic of left side. I think not showing left side may well have been deliberate, as the 97 makes it more valuable.

 

nothing wrong with a 48 though especally on a OHV motor
