Rebuilding A Weber 32/36 Dgav Carb

[Guest mr D]

Found this on another site thought it might be useful to someone it seems very comprehensive and plenty of piccy's

Excellent find!

[Guest Hoppo]

Very good and I have just paid £67 to have my carb cleaned out and a new gasket set and choke diaphragm fitted

[Guest peter2b2002]

just had a look just as well as I have found a small pipe at the back under the choke, I wondered what it was now I know its the vacuum take off for the dizy, that might explain a few things

Unfortunately the link no longer works, does anybody know a way to set-up a brand new 32/36 DGV carb, picked up a 2B today & it's running a bit rich  so rich I'd be popular in MaccyD's carpark banging & popping like a good 'un.

You say dgv has it got a manual or automatic choke? Looks like it could be stuck on 

[phaeton]

It's a manual choke, I'll check tomorrow but I do think it's coming off as if you pull full choke it won't start.

Edit:- Just to add on the invoice it says Weber 32/36 DGV 5A Carb Model 22680000500-6 if that helps

Dgav  is the auto one. If you look down the top of the carb you should see the choke butterfly moving.
It may be the float needle Valve not closing properly causing it to flood.

This is what I am hoping, if ever the rain stops I'll try to have a look

Got the toffee hammer out this morning & gave the carb a few gentle taps around the float chamber, didn't really want to strip it down if I can get away with it, pulled the plugs out & found some of the sootiest plugs I have ever seen. Gave them a clean up & reset the carb back to 2 turns from the stop, after that it fired straight up, still a bit rich I think but the ignition timing is a bit off, I think I need a new rotor arm & cap. I put my timing light on at one point & it was missing sparks on No1 cylinder so hopefully get them tomorrow.

What is the standard timing on a 2.0L Pinto?

[Peter Bell]

Think it’s about 8 degrees btdc. 40 year old dizzys get quite worn, if they are points type they can miss a spark. 

[phaeton]

Think it's been changed to an electronic one, although I suppose the shaft could still be worn
