sold to Little dark Stallion

Yeah I know the one, I noticed Ian had one lying around one day so I gave a good looking over, they're quite compact too.

Weber did make the throttle shafts on these carbs in two versions, clockwise and anticlockwise. its just a matter of finding one

One of the single biggest tips to do when fitting the "DG" type carbs on the std datsun manifold, is to open up the mounting flange with a die grinder. remove the bridge section. I ground my one while the adptor fitted as to match port and make everything nice and smooth [not polished]. it's all about air flow.

I was tempted to fit a 40 DCNF [a twin throat syncronous 40mm carb] on the A12 to see how it goes. Just haven't got arround to it yet.

I was considering one of these for my 15. Is the main shaft rotate the same direction as the 32\36 or is it reversed? I quite like my throttle setup so i don't want to change it, even for side drafts but they have enough parts that I shouldn't have to.

D,

Cheers for the info. I revised my financial status and admitted that I'm not in the position to make a purchase.

Disregard my interest in purchasing.

Good luck with the sale.

The adapter plate is tapered for 28/32 inlets so that sits on top of your manifold.
Then the carb on top of the adapter. I dont recommend you use this
on a standard A10 as it would only benefit if you used some sort
of fast road camshaft to get it to flow properly.
I always think an early a12 is a nice motor for the b10
and you stash your a10 away in the shed for originality.
Or do what Dodgeman Chris has done with the A14 within an A12 hybrid.

Once re-jetted for your application and if the application is mild/warm/hot
then you can expect the air velocity and fuel mix to be better than a single 45mm
weber for the road as its designed for all round performance rather than top end.
A single 45mm twin weber requires a serious cam to get it
moving and then its a pig to drive in comparison to a downdraft
with more complicated flow path that improves torque.
Its really what is considered a grunter carb where unlike the twin
hitachi which have a delay in acceleration you get instant throttle
response also. Even hillman Imps with 875cc used a single 40mm weber
sidedraft as the 45 takes to long to reach optimum air velocity for proper fuel mixing.

how would these go versus twin hitachi su's on an A15? im thinking of possibly selling the twins and going back to a big single.... would also need manifold to suit.

Hello D,

How'd this go on an A10?

I'm interested.
