38DGAS help please - now sorted
I have a standard 2.0l Pinto lump. Head refurbed and fitted with FR32 cam. 2nd hand 38DGAS fitted. I have noticed a fuel leak when i completed fuel
supply tonight. Carb has 2 toothed quadrants that open both choke flaps together. Oposite the quadrants is a device that i think is called a
accelerator pump. It has an arm that moves as the chokes open up. Fuel observed leaking from this arm. Is there a diaphragm behind this that is likely
to be perished. I think i need a refurb kit - does anyone know if the diaphragm etc will be part of a refurb kit? Does anyone have any reference
material for this carb to assist with a strip down and rebuild or can anyone recommend a good book.
I have never stripped a carb before so any advice is greatly appreciated.
Thanks in advance,
Darren.

You are on exactly the right track. It is indeed the accelerator pump (when you open the throttle it squirts a jet of petrol in to mask the flat spot
as the airspeed through the carb picks up and starts to draw fuel off the jets)
As far as I can remember, the diaphragm is part of the rebuild kit, if you check with Burton's ( Tel. 020 8554 2281) though they'll let
you know for definite.
The rebuild itself is nothing to be afraid of, just get a can of carb cleaner or some cellulose thinners, an old toothbrush and newspaper to spread
everything out on and be meticulous, that's about it.
Cheers

Darren,
Just found the same problem with the 32/36DGV carb I am using. I have ordered a rebuild kit from Burtons for about £14, which has all the parts,
gaskets and seals you need.
I've not stripped acarb before, but as NS Dev says I don't think it's too difficult!
Cheers
Nick

Thanks guys. I managed to get hold of the Haynes Weber manual as well. The diaphragm has perished. I managed to get it away by wiping some bond and
seal onto it with a cloth. It has made a temparary repair whilst i sort a kit out.
I whipped the top off the carb and was surprised by how simple it looks underneath. The manual actually makes it sound more complicated.
Thanks for your help. Ill give Burtons a call.
