I second buying a new one in a kit.
I had the joy of buying 2 on ebay ( 1 as is {paid way too much} the other "remanufactured" {sort of}) I had to fabricate the throttle cable, the carb adaptor plate listed in the application guide didn't fit the manifold, after several times or trying to find the right part #, I ended up making my own adaptor plate. The comes jetting. I recommend paying the carb shop to set it up (if your car isn't illegal) since tuning and buying jets is way more $ than they want. You might want to get an EGT gauge or a wide band o2 sensor to help with dialing it in.

but on the up side...
you'll know so much more about your car.

I learned enough to stop burning gasoline.

also is it better to get a brand new 32/36 with the full kit or should i get a good 2nd hand and source the rest from redline. also how much work and what sort of work would be needed to get the weber to run smoothly on an a12 with extractors

cheers
joey

Where do I source a 28/32 from? 2nd hand of course.

I think Any Carb would work Depending on how mutch effort you put in getting it sorted. I prefer the weber, because of its sound and the way it goes if you open both choke's . More air is what you want. 32/36. is what i say.

so what would be the best option in terms or performance and functionability a 28/32 or a 32/36 with the right jetting

I run a 36/36 dcd 7 on a A14 engine Dead STD except for an Electronic Ignition. No problems, no idle'ing isseus . I would recommend get the right jetting for the A12.

they make a smaller weber 28-32 thats more applicable

in that case then, what would be a recomended carb for a stock a12 with extractors, since the 32/36 works better for 2L

cheers

I run a 32/36 but it is on an A12 with ported heads, bigger valves, GX cam and extractors , plus it only gets track use. The idle is ok and the carb works well......I also like the much maligned SU types and had no problems. I only switched out the SU type because I was doing a tarmac rally which required the car to get a smog check to be road legal.
Now on a Plymouth Arrow (Mitsubishi) I had a 32/36 and it never really idled great, ran fine but idle was eratic. In the states used 32/36's in good order can be had for $50.

an A12 is at the very bottom end of workable for the 32/36.
you'll probably have idle problems ( too high or it dies )

what it comes down to is the 32/36 is not the best carb design.

I'm learning to have some respect for carbs like the SU's found on the roadster.

I had problems with the secondary sticking open slightly and that would make the car run all schitzo.

I gave the same carb to some kid after i dug it out of my trash trash and it worked fine on his over 2 liter engine.

Some people love them. Personally I really like the variable piston carbs - especially in LPG apps.
