Some help with a Weber Carborator?!

[Zeehenk]

Hi everyone!

I'm experiencing some trouble with my Ford Transit MK4 (1993) campervan which seems to come from the carborator. I'm looking for a service set so I can clean the whole thing and replace the linings. Can anyone help me with correct model of this Weber Carborator? Attached a picture of the serial number (Weber 92 HF AB AH 075 3)

Note: Our van is an MK4 from the looks, but seems to have all the specifications of an MK3. Not sure if this helps. haha

Thanks everyone!

Edit: it's a sings valve gasoline carburateur

put into ebay the words

weber DFTH 30 34

and you will find the overhaul kits

plus a new one at £135

put the same words into google and there are many kits, many carbs and even free manuals on how to rebuild them if you put pdf after weber DFTH 30 34

Thanks Mark!

Just out of curiousity; how do you know which kit/ carborateur you need to buy based on the given Weber (serial?)number? I'm lost in these seemingly random letters.

when i put your numbers into google, lots of forums, sites etc returned the results saying DPTH 30 34

and here .. other suggestions including weber DFTH 30 34

viewtopic.php?f=2&t=93422&hilit=weber

there is also other replacements

Weber 34ICH

any of these may have the wrong jets in.. as the sellers are full of misinformation

myself .. i had a pierburg 2E3 on a 1.8 pinto in a sierra and kits for that are much more common and cheaper

is it a twin choke? if so it never came on a transit so will never be jetted quite right anyway

[dumper]

Fitted loads to pinto’s back in the day never had a problem the only ones I had to rejet was when fitting the ones off a V 6 for more power but a bit thirsty but good for road rallying

bortaf is letting you know, he thinks its got the wrong carb on it

May run well once rebuilt .. that you'll find out .. the main thing that goes on old carbs is the accelerator pump diaphragm, , the auto choke, sediment and calcification of small passages and jets( ultra sonic cleaner needed), float height. all easy yo fix. and the spindle holes wear on the butterflies.. makes air leak, leads to hesitation and fast tickover , lean mix at tick over and difficulty with tuning.. fix is bushings after drilling them out to size.

me too fitted loads of carbs to loads of engines and they ran ok just not perfect

in thoery the 38 dgas is a much bigger carb, 2 38mm throttles compaired to a 32 and 36,
but if you dig deeper you'll find the 32/36 has 26/27mm chokes and the 38 has a pair of 27mm chokes,
in practise means the 38dgas wont actually flow much more air than the 32/36, and if you get the wrong model of dgas the low speed progression stuff is crap, where the dgas does make more sense is with lumpy cams, having two sets of idle drilling means you will get a better idling motor if you have a hot cam.
dont forget the transit LC engine uses the lower lft 1600 cam and i found the TC a bit "fluffy" in the lower revs (if that makes sense) ?

but i digress

At least it's not a VV

When I’m talking about fitting the V 6 webber it’s definitely not suitable for a camper or commercial van it’s down to the most power you can get out of a engine

32/36 doesn't work pefectly on low comp transit engines with 1600 low lift cam IME, as i said a bit fluufy in the low end when giving full throttle, it runs lean, less air velocity through the carb (because the carb venturi(s) is/are larger but the same amount of air is drawn through it) equalls less fuel pulled from the jets, less air speed also means less torque, rejetting needed, single choke carb = higher velocity in the inlet and more lower end power, thats why ford fittem them, changing the power delivery characteristics of the engine to suit weight carrying.

ok i did go off on a tangent as i tend to do lol so sorry but

38 DGAS, only usefull with tuned engines and lumpy cams for the reasons i stated above (thats a rough copy of a dave walker quote in a mag years ago) it simply can't produce more power because it does not flow much more air than the 32/36, choke sizes are so close as to not matter, i thought and acted the same as you for years until i got serious and started getting my cars set up on a RR then i saw what you will see on the vid below, it matches my findings on 3 differant RRs i used over the years, the dgas feels quicker on the road, that i cant argue with, the sudden rise in airflow Vs the porogressive step of the 32/36 is evident.

Don’t we all yes anyway back to plot the v4 to 2 lt pinto mk 1 conversion of mine I rebuilt a engine for it low compression piston and 1.6 camshaft and a brand new Weber twin choke from the local official Webber dealer and as you say it had to be jetted differently by him he got it spot on when run in it needed nothing changing

I've just learned more about Weber carburettors in that post, than in all my messing about with Ford cars back in the seventies and eighties. Magazines would write about fitting this and that, changing jets, etc without any real explanation as to what the different results would be on the car.
I never managed to get rid of the flat spots which existed on both my Escort 1600 Sport, and my dad's Cortina 2000E, flat spots which were thankfully non existent on our next cars, both of which were fuel injected.
I was more successful with SU's

I will split the post if the OP wants me to restore it

[dumper]

Yes Al fuel injection is so much better then carbs the only problem I had with my 1600 sport was the K&N filter the carb iceing up in winter the last car I had with a carb was my XR3 the auto chock was a bit hit and miss but the XR3i was the first injection car I had and was a game changer
