Weber Carb Identification

Post by Ollieoldbeard » Wed Dec 09, 2015 9:11 pm

Is anyone familiar with the numbers stamped on the metal tag on Carbs, my Se6a (79) is suposed to have a Weber DGAS/3A but doent exactly match any of the diagrams in the workshop manuals, the stamped numbers & letters are; Weber 772F AA, A 9B23
Any ideas ?
I want to take it off and clean it as its suddenly not running and running lumpy as it gets warm, it seem theres a problem with auto choke, it sounds too rich rather than starved but im no expert, any thoughts ?
Thanks

The number(s) you're after are stamped on the side of the base. Unless someone has fitted DCOE carbs to yours though, it could confuse this thread.. I'm on my phone at the moment so can't split this off to a new thread for you - Roger/Luke can you oblige?

Right. Solution delayed due to the impending arrival of Christmas, leaves on the line, poor weather conditions, and the wrong kind of rain...blah....blah....blah.... :wink:

Hopefully I've made some sense of it

1. This thread is the original sticky for Standard Carb Jet Sizes

2. This thread is the thread for discussing the re-jetting of Triple 40DCOE carbs on the Straight Six

3. And finally, this thread wot we're in 'ere, is to do with identifying the identification of carbs on the V6

Any ideas ?
The numbers on the tag are AFAIK the Ford part number for the carb (they roughly correspond with the numbers in the Parts List), but they're relatively academic in terms of accurately identifying the carb. The important thing as Phil says, is the number stamped on one of the short sides of the base.

ok i will have to go look on the base, as for all the Jet sizes is that for the "tamperproof" DGAS carbs too ?
i heard that GW do service kits for the carbs, are they easy enough to take apart, clean and regasket without bu##ering them up ?
my auto choke has no hoses going to it or electrical connection (as far as i see) probably why its so troublesome (DGAS/3A in manual, if not changed)

Yes and yes to the first 2 questions. If your autochoke doesn't have 2 water hoses attached it will never have worked properly. It will be a 38 DGAS, the 3A is just a version and may be a 4C.

Thanks Jim, it seems theres no connections for water hoses or electrical, plus the water hose passes straight thru to the matrix in bulkhead but the is a join right opposite the carb, so it must have been changed, i wonder why, probably with the manifold..
The numbers stamped on the base of the carb are; 035414 does this mean anything to anyone ???

Unfortunately I can only just about use this forum for writing I've got no idea how to post pictures or the time to work it out, but I could text a picture to someone if I had their number and they have an iPhone

Weber Carb Identification

Post by scimitargtc » Thu Apr 11, 2019 7:50 pm

Stupido Q.. in this thread it appears to choke flaps are fully closed?... is that normal? I ask as I was about to fire up mine this afternoon (finally as this stage has taken me weeks to get to instead of the couple of hours I told the wife) and just before I turned the key noted both flaps were fully closed opening them gently by hand they snapped closed as if against a spring. Now I know it will be my fault whatever it is as I had it apArt last Friday to clear out the float bowl etc so it was in many many pieces on the worktop

Choke flaps should be fully closed when cold - after setting them by pumping the pedal a few times.
