Stromberg WW carby info

oh cheers Chrome Yella yea i cant find anything on it

Leyland sourced alot of parts from other manufacturers.

I'm looking for some engine bay pics of std WW Stromberg set up from the GTR Torana & the 186S HR Holden. Pics from the linkage side of the carb to the fire wall it would be very helpful.

i know the post is old but Just looked at my WW Stromberg, only numbers it has is in a circle on the side of the barrel,

23765||
|316

and on top it has

A2
3 40


any ideas?

thanks

Hi Phantom10 / chrome yella,

Did you manage to confirm the vehicle your WW Stromberg came off? I am having the same difficulties confirming the details of mine - I purchased a 186S Holden manifold complete with carby and although I was told it was it came off off a 186S – I'm thinking it is now off a Leyland 4.4Ltr P76 (not that I'm too concerned) but now I want to ensure I have the correct main jets, setup, etc running on my 186S red motor.

My WW Stromberg Details

23 765 II

1 3/16
213 in Diamond Shape

Top of Housing
A 6
4 13

If it is indeed off a Leyland 4.4Ltr P76 – is there is anything I need to look at changing in my carby since I am running it off a 186S red motor (stock – no go fast gear, just solid reliable engine)? I took my cylinder head off the other day and it looks like it's getting too much fuel running through it.

Any help would be greatly appreciated.

Cheers

hi, i have a ww stromberg on my mild red 202 and its literally falling apart, been doing it for a while but it kept working so ive never done anything about it..
till now.. ive bought myself a fully rebuilt ww stromberg and im assuming it has the same jets as the old one ive got on the car now, which are way too big for it..

what jet sizes would be good for my engine and where would i find a place that sells jets and how do i go about changing them over..

also i would like to know where i could download information on how to tune these things so i can put it on the car myself and take it to my mechanic for some fine tuning..

would these work or are they only for single barrel strombergs..

The jets will work but for best results you would have to get it dyno tuned. Better off with fixed jets IMHO.
Those tools are correct to replace them.

More details one what carby you have and what car it is going on would be good?

There are different power valves too and wont interchange from early and late WW2

yeah i was thinking fixed jets too but thats all i could find with a quick google search..

the car its going in is a LX 4door with a red 173 that i have been told from the guy i bought it from about 8 years ago has been bored and stroked to a 202, a bit of a lumpy cam, extractors, i want to put elec dissy on it soon..
other than that i have no idea what the engine is..

the carb is a WW Stromberg Carb 23-3093 rebuilt by these guys.. http://stores.shop.e...LP-Carburettors

cheers adrian

the carb is a WW Stromberg Carb 23-3093

23-3093 = 75-6 LH-X;HJ 253 MAN

A bit of a guide to jets:

MAIN JETS
186S .053"
253 V8 .050"

POWER VALVE
186S #56-56 drill
253 V8 stg 1 .032", stg 2 .055"

IDLE TUBE
186S #70 drill
253 V8 #71 drill

You can see in the yellow that the power valves are different.

Throw it on and get it dynoed would be the best way to go.

ok thanks for that, i might give it a go this weekend if weather permits..
#56 drill is 0.0465" going by http://bobmay.astron.../drillchart.htm

Litegy - you'll have a 48, 49 or 50 main jets.
See Rodomo's post above - you'll want 53s for the 186, maybe 52s if you have a big cam.

Grant..

ive spent a while trying to research this topic but i cant come up with anything. my strommie has the numbers 2376878 cast onto the mounting plate. now the only reference to the 7 i have gathered is leyland but the other numbers dont match the accounts of have seen which start with 7 after the holden code (23).

any help?

also another question i had was what is the original carby on the red motors, what is the significance of the 'WW' type stromberg carby?

on second glance, i think the carb is actually as 2326938, this number is actually located on the back within a small circle, the other number i pulled off was on the mounting plate after i gave up on finding any numbers on the carb. though, still no results from searching google

in fact there are bloody numbers all over the carb, i found another one in a circle as well which reads 2376618

Hi All,

Did anyone actually confirm whether WW Stromberg 23-76-511 is from a P76? I have the same carby numbers on top of my 186S HR. Does not start real well, idles crap until slightly warm then ok and at WOT, goes like the clappers. Exhaust is definately black, which would explain the larger main jet in the P76 compared to the 186S. Inside carbie is clean and shiny.

Ideas appreciated.

Thanks,
Geoff

That number is only a casting number.
Need the number on the top of the carby looking straight down from above.

Both mine have 23 3020 but one has -9-48 and the other has -8-44 after the 23 number, anyone know what those numbers are for, they are both 1 5/32.

23-3020 single throat off a HR-HG 186 manual.
The other numbers are a date code. I think it works like this -9-48 = 1969 48th week.

Cheers Louie

mine is 2376402 then 3 and 16????

Hi
Just wondering what oil people use in the damper's of their 175 Stromberg's ?
My carby builder said that a real thin oil makes the car run leaner.
Cheers

ATF

What the dampener does is govern the lift rate of the piston. Think of it like a shocker. Therefore, the thickness of the oil used in the dampener affects the lift rate speed.

 

As SU's or CD's have no accelerator pump, the lift rate is what governs the mix under acceleration as vacuum will act on the jet drawing in more fuel as the piston lifts.

 

Thick oil, piston lifts slow, more fuel, less air = rich.

 

Thin oil, piston lifts quicker, less fuel, more air = leaner..................................But...............Only under acceleration.

 

I think you need a new carby builder?

I agree with the above. 

 

Your carby builder has no clue. 

 

The needle and main jet are what govern "rich" or "lean"

 

The damper springs and oil purely dictate how fast the needle rises away from the jet, which in turn governs the orifice the fuel cam come out of. This is coupled with the piston restricting the venturi size, thus dictating the air flow, which directly affects the amount of pressure drop and therefore the amount of fuel drawn from the jet with the needle in any given position. .

 

Oil in the dashpot is a tuning device for driveability and performance for a given combination, like the vac sec module springs on a 4bbl vac sec holley. The main jetting is done elsewhere. 

 

Cheers. 

Thanks Rodoman
Yes ONLY under acceleration,he did mention that ( sorry forgot to say ). I'd agree with all of the above, so what oil do you guys use please.
