Jarrid,
Thanks for the info, it raises a number of other questions...
My car is a roadster, but has WIA-3 carbs, with a black 'pancake' on top
which is piped to a giant air cleaner housing mounted on the inner fender,
it has a paper element inside.
My manual agrees with you, but a couple of other sources said the WIA's are
correct.
A local carb shop has quoted to rebuild my carbs and said they would fit
bushes to the body of the carb to fix the leaking throttle shafts. If the
wear is in the carb body this is good. If the shafts themselves are worn,
this won't work - do I then need to search for good second-hand shafts?
What are the shafts made of and why hasn't anyone reproduced them? Do many
people still run the downdraught Zeniths? What about turning the shafts
down, then bushing the carb body to suit?
Does wear around the choke shaft cause the same problem, or is this before
the fuel is metered into the carb?
If I rebuild these carbs, should I keep them as WIAs or change to WIPs? I
understand the "power valve" is really an economy device and is another
source of problems, so I would happily remove it. Are there any other
considerations? I will need to change jets, etc if I change them to WIPs, as
I have read that these are different between the two.
Other options? (Remember I'm in Australia, less stuff for Alpines here)
Twin Webers are too expensive, I'm only cruisin', and I don't fancy setting
them up.
Single Solex is not a good carb, I have heard, would need a manifold too.
Single 40DCOE Weber - possible, but I may have trouble getting a manifold,
still costly
Twin single downdraught Webers from a VW, bolted onto my manifold -
interesting, but risky
Leave my stuffed WIAs on the car, buy a pair of WIPs, rebuild them and then
fit them - looking better all the time...
Cheers,
Paul.

If yer Alpine be a GT, It should have the paper element and 36WIA-3

Otherwise, It should have the Metal Gauze elements and 36WIP-3 carbies.
There are no actual differences between the carbs as far as rebuilding
goes,
except the power valves "or lack therof" used on the WIA carbs.
WIA carbs are convertable to WIP and vice versa.
As far as rebuild kits are concerned, there is only one, and it includes
the
power valves.
Dont waste your money on the carbs if the throttle shafts are worn.
The zeniths are good carbs, but run pretty poor when the shafts start
to leak any significant air around the butterflies at idle.
We really ought to find someone to make some shafts up as they are not
available.
