weber carb/manifold question
Hi Guys
Question about Weber downdraught carbs.
My 1800 Pinto has the PIERBURG carb
I want to change it to Weber.
Looking on the Bay there are manifolds for 1600/2000. but nothing showing for an 1800.
Are they all the same?
2nd question. Which carb should i be looking for.
seen a WEBER 32/34 DMTL
But it's just numbers to me
Any help would be appreciated

IIRC from my lesson (just the other day  ) i think the number is the diameter of the hole.
How long can i resist the temptation to drop a V8 in?

Weber numbers are the size of the bore where it mounts to the manifold ie; 28/36, 28 is the bore of the primary and 36 is the bore of the secondary.
The carb normally runs on the primary, at 3/4 throttle the secondary opens giving more performance. So yours has a 32mm primary bore and a 34mm
seconday bore.

1800 engine was just a variation on the 1600
2 litre had some diffrences that aren't obvious.
I don't the Pierburg (formerly called Solex) bolt pattern on the manifold on your engine but on Vauxhalls and ancient Rootes engines Weber
carbs bolted straight on the original Pierburg/Solex manifold.

You can use the 1600/2000 manifold and a 32/36 DGAV or DGV carb which was standard on pinto engines.
I have attached some info to help
