Also try piercemanifolds.com. Go to the exploded view of the carb. It has the parts numbers listed. Click on the number of the part you need and you will see if they have it or not.
They have more parts than Alfa1750, but Alfa1750 has some parts that piercemanifolds does not have.

hey guys
so im going to be selling my '85
My built 4port 13b is going to stay though, im going to put my engine in the gf's 79 and put her stock 12a in my 85. However i want to keep the dual carbs from her engine and put them on mine
soooo i need a 13b manifold. Does anyone have one for sale or would like to trade for the RE dual intake manifold off the 12a ?
THen i'll just pick up a stock nikki for the 12a and sell my weber 48ida set up that i had on my 13b
i've been checking ebay with no luck :/

i have since bought a good amount of jets (air and gas) for it and it came with some extra e tubes as well, so there's a lot of stuff that goes with it. To be honest i'd like to get the duals on my 13b before letting the ida go. However if you were interested i could certainly give you first dibs on it?
To make matters worse im deploying to the sandbox for a quick 4mo tour next tuesday, will be back in january. but i have my mind set on engine swapping, trying to get the duals on my 13b in the gf's '79 LE and selling my 85 with a stock 12a in it
Would you consider letting one of those 13b manifolds go? i'd offer you a 12a in trade but it sounds like you wouldnt have a need aha

Let me check the carb storage section upon returning to the shop.
Feel free to holler if you haven't heard back in a day or so.
I also have all the info for jetting changes from 12A to 13B (stock or street port).
These work well on a stock port motor but street port is a whole nuther animal.
Even with the correct jetting values, there were some tweaks that Rotary Engineering did - such as custom drilling of the emulsion tubes. Very few people actually go to that degree of detail.

Nice looking rims. Are they non 13's? Given the limited choice in 13 inch tires, it is just a matter of time when 13 inch tires will disappear.
Where can I some?
A classic tribute to wire wheels of british sports car when they were worth damn.

I don't see how this is 36dcd related lol but both tire rack and discount tire should have 13" tires...

The selection is considerably less now. If trends continue, there will just be race track tires. So I could use 13 inch ATV and trailer tires and rims?

ah I should have known what you were referencing...
tires concerned, yes you "could", should you? no probably not. Did you click on the amazon link ? there's still a good amount of options out there for you listed under passenger car tires. the trailer/atv tires remark was just that, a remark lol
click on the link if you haven't yet, decent tires for cheap prices

regardless I think 13" passenger tires will still be available in the next few years and there onward.
hey if I needed to get somewhere or push my car around I wouldn't be opposed to putting atv or trailer wheels on the car to move it around.
The wheels themselves, ive seen some pretty attractive trailer wheels, tires wouldn't be good for over 70 for the most part from trailers.
Atv's,, im JUST saying most atv bolt pattern is 4x110 lol ive never done it but just listing options.
Getting a little off topic now

There is no performance level tires in 13" that are not RDOT or pure race tires anymore and
there are none of size 205/60x13 except rdot and race tires. Any stock sizes out there in
13" are only suitable for mild street use, if that.
Do not use ATV wheels or tires, they are not even close to being designed for the weight
of a car and the G forces a car would put on them.

Back to the weber carbs. Can someone pleace give me the exact length of the two choke cables running to each carb from the Y splitter. Mine didn't come with the carbs nor do I know where to purchase it. Pictures would help too!
Thanks!
Thanks!

then on the point of the triangle Y splitter closer to the driver side there's a hole for a choke cable to go through and another set screw to pinch it in place
so the whole system is adjustable
kind of hard to explain w/o pictures, hopefully I described it well enough.
EDIT: see my crappy drawing from paint below for what my dcd's have for the choke

Thanks! I'm mainly looking for the length of the two cables where it splits and are they the same length, etc? Pics of how it attaches to the choke levers of each carb wpuld be nice too.
I'm in BC now so I'll check out some bike shops but I do need the specs to tell them what I need in cable length :P

I'm sure you are wondering what this has to do with a RE Carb Manual, but I had the Rotary Engineering Carbs, kit, and manual in the car that I had bought from a Gal on this forum (under another Username I forget now) in New York and the Manual was in the glovebox when the car was impounded. The manual you have pictured there has the same exact pencil marks on the last page that mine had so right when I saw this post while looking for RE carbs for my 1979 my interest piqued. I know it's been at least 10 years for this post here and more for me, but if you had any contact that would be amazing. Always wondered what happened with the car since it was my first RX. The car was a 1984 RX7 with the 12A, RE Carbs, Racing Beat Exhaust, Horrible rattle can paint job, DZUS Fastenered Fiberglass front air dam, and at the time I had Spec Racer Ford sized Road Racing Slicks on it, gutted interior with just the dash and 2 front seats.Figured I'd give it a shot. This is a much older shot of the car from just after the awful paint:

We obtained one of the Rotary Engineering Weber 28/36 DCD carburetor sets from the company back in the late 80’s. It was a 12A stock configuration to start with and then was reworked (by R.E.) for use on a 13B street port.
One set is currently running on a Rx3 open track car w/ a 13B street port and another on a daily driver 85’ FB w/ a 12A street port.
Over the years we have compiled jetting information on fourteen of these dual carburetor sets, both stock and street ported, 12A and 13B. Several of these sets are also in storage. If anyone would like setup information regarding these units, feel free to contact me.
