Do you know if all DHLA 40 emission carbs are the same, or are there several versions of f.ex. the DHLA40H with progression holes for different engines? I know that the DHLA 40 performence carbs are specific for the size of the engine (ex. a DHLA for a 1300 on a 2000 will have an uncurable lean spot due to the progression holes)
I have install weber 50 doe in my ford cortina , and the engine cant running, i dnt know why . I need your suggestion for make it run, sincerely from malaysia

The number is not important, it is the matching of the numbers between the carbs. The master carburettor is the one with the throttle lever, and the slave carburettor is the one with the balance lever (one with the springs attached). The slave carburettor gets adjusted - by using the airflow meter to take the reading as you adjust it - to match the master carburettor. if the master read 4kgf , the adjust the slave , so that too, reads 4kgf. it could be 3kgf, it could be 6kgf, it doesn't matter. just match them up. obviously 6kgf, is flowing more than 3kgf, 6kgf would have higher idle rpm, than 3kgf. Also, use the meter, to check the airflow on each barrel of the same carburettor.. this will tell you if the barrels of the carburettor are pulling the same ammount of air. if there is any significant difference in airflow between the 2 barrels of the same carburettor, it means that your spindle is bent, or the throttle valve/butterflies are not sealing the barrel correctly, and you won't get the engine to run well whatever you do. you will need to strip the carb, and repair the fault. if the 2 barrels are matched up nicely, and drawing in the same kgf, then you are good to go ahead and balance the 2 carburettors, and do burnouts.
The 151 model has an adjusting air bypass screw for each barrel, why not using this to adjusting the flow after we adjust the 2 carbs? Or when is the right time to adjust by there? Tnx
Hi, This one had a fuel pump + fuel pressure regulator. You could just use a WFP502 pump, and use it without a regulator: classiccarbs.co.uk/product/weberdellorto-twin-40444548-carbs-12v-electric-fuel-pump-dcoedhlaidfdrla ALternatively, a Facet pump + pressure regulator combo like here: classiccarbs.co.uk/product/weber-dellorto-solex-su-carbs-facet-electronic-12v-fuel-pump-kit-200bhp And the fuel pressure regulator: classiccarbs.co.uk/product/weberdellortosusolex-carbs-malpassi-fuel-pump-pressure-regulator Thanks, Emmanuel
I have install weber 50 doe in my ford cortina , and the engine cant running, i dnt know why . I need your suggestion for make it run, sincerely from malaysia
I used a simple airflow gauge on my Samarai twin Delorto carbs. Worked well. Adjusted mixture with a quartz see through spark plug.
2 videos in 1, how to sync carbs, how to drop a valve while trying to sync carbs.
Thanks for the video. Very informative
Hold the camera horizontal...no cinema screens, tv,s or computer monitors are vertical format.
Will do, thanks 👍🏼
Your lucky to get some sort of a tick over with very high lift cams and DCOEs
what do you mean?
They normally run like a sack of shit until on cam
I had the throttle cable get stuck wide open on my Westfield. Bloody scary stuff I tell you!
What air & fuel jets used in these 40s
thats beautiful!!!i need these on my pinto
Hay , get 2.4 , than a Volvo 2.4 allunimin turbo head and turbo exhaust ,will fit and match blockcheaper OR TRK head
How can I get one of those carbs???
iam using 7 port mini.what is the best jetting for using 40 dcoe twin weber for my engine 1380cc
Hi there great video .. Just a quick 1 my side drafts making a whistle noise what could it be
Sounds like an air leak.

I guess my question is; do all DHLA40H emission carbs have the exact same progression holes?
@@thisquietplace there are different amounts of progression holes for the later dhla 'emission'
@@thisquietplace everything after a Dhla H is emisson variant
LOL that was hilarious to watch haha. Good video tho man

I have single cam 70s bmw 4cyl engine with weber dcoe twins, I have weird issue that it backfires on only number 3 cylinder sometimes, any tips?
Do you mean spits back out of number 3 carb or backfires from the exhaust?
What is the difference between dellorto dhla 40 carburetor, dellorto dhla 45 and dellorto dhla 48
It is the size of the inside diameter of the barrel, 40mm, 45mm, 48mm and effects the volume of air and the speed of its flow
What manifold is that?
What should be the right number on the meter? I need to set my 40s. Ta
The number is not important, it is the matching of the numbers between the carbs.
The master carburettor is the one with the throttle lever, and the slave carburettor is the one with the balance lever (one with the springs attached). The slave carburettor gets adjusted - by using the airflow meter to take the reading as you adjust it - to match the master carburettor.
if the master read 4kgf , the adjust the slave , so that too, reads 4kgf.
it could be 3kgf, it could be 6kgf, it doesn't matter. just match them up.
obviously 6kgf, is flowing more than 3kgf,
6kgf would have higher idle rpm, than 3kgf.
Also, use the meter, to check the airflow on each barrel of the same carburettor.. this will tell you if the barrels of the carburettor are pulling the same ammount of air. if there is any significant difference in airflow between the 2 barrels of the same carburettor, it means that your spindle is bent, or the throttle valve/butterflies are not sealing the barrel correctly, and you won't get the engine to run well whatever you do. you will need to strip the carb, and repair the fault.

@@Classiccarbscouk blimey that sounds difficult but I'll give it a go. Thank you ✌️❤️🙏

Nice job. What did you use for a fuel pump and did you use a pressure regulator. Cheers
Hi, This one had a fuel pump + fuel pressure regulator.
You could just use a WFP502 pump, and use it without a regulator:
classiccarbs.co.uk/product/weberdellorto-twin-40444548-carbs-12v-electric-fuel-pump-dcoedhlaidfdrla
ALternatively, a Facet pump + pressure regulator combo like here:
classiccarbs.co.uk/product/weber-dellorto-solex-su-carbs-facet-electronic-12v-fuel-pump-kit-200bhp
And the fuel pressure regulator:

Thanks,
Emmanuel
Its worth it to get regulator tho, easy install, saves fuel, cheap, +its good idea anyways to have stable pressure
would like to know does the jets play a massive role in the tuning of the carbs .
thanks ! when it comes to a A12 do you perhaps know the perfect jetting size for it. i have a set of DHLS 40s side drafts and i'm really not sure
thanks for the response Emmanuel the size of the A series engine is 73mm (2.874 in)
Is that a dodge 2.2 2.5 engine??
No, it's a 2L Ford SOHC pinto motor
Why the rpm goes up?
Well that all went to plan.....NOT
I wouldn’t let him touch my engine. It’s pretty obvious he doesn’t know how to tune those side drafts.
No one wants to touch your engine anyway
Mk1 ? Don't you mean mk2 escort lol .
It aint a ''PINTO'' FFS its a normal 2000 OHC,made in Dagenham or Cologne with a few add ons,nothing like a pinto,different beast all together
