I completely disassembled the carburetor from Suzie Belle for a cleanup and new parts kitout.
At the top of each throat there's an air nozzle needle thing about an inch and a half long, with tiny air holes at the base of the needle. One has a hole in the top and one has a hole in the side, near the thread.
I stupidly forgot to check if they were different when I pulled it apart for cleaning - they are!
So can anyone tell me which side which air needle thing goes on?
I'm uploading a picture with this - it might not work though.
Any help or advice would be greatly appreciated, I'd love to put this thig back together and get her running!
Thankyou.

Sorry for the blurry pic. The bits in question are the brass slotted thing stamped "60" and the corresponding one above it which is darker and has no hole at the top. This picture is post-cleaning.

come on guys someone knows this answer ...give him a help ...cheers davo

ill have to go to work and have a look at my spare carby! ill try to remember to bring it home so i can have a look for you!

Hey there Ledmeterman,
I believe you have it correct. These are the Primary and Secondary main air bleeds. The secondary is the one with the hole (on late series carbs) and goes o=in the secondary throat, nearest the fuel bowl inlet pipe.

Sorry about the slow reply, hope it goes well for you.
Cheers, Matt.

Cool! Thankyou so much for the help. Now I can leave the carby on the car rather than removing it all again! I did up the fuel pump and did what I could with the old filter - but the pump isn't what it used to be and I think I'll have to install an electric one back near the tank somewhere and put in a regulator so as to not flood the thing. I'm wondering if a regulator would be better before the pump or after? If it was positioned before the electric pump in the fuel line then there would be no chance of too much fuel anywhere and possible leakage..? Or is my theory defunct

your asking the right guys about the fuel pumps if you look thru past postings there was an article about blocking off the fuel pump and using an electic pump ...anyone out there remember ??? i too would liike to be prepared cheers davo

I have 2 cars running on a facet pump with the nikki's 4 /6 psi with no pressure regulator they run fine.

Hi Ledmeter,
how did you go with the carby?
I'm sorry I don't get on a computer very often, but my workshop manual goes into great detail on these areas. Let me know if you still need help ( I will set up for e-mail notification ).
Cheers.

Hi again,
I like the mechanical pumps 'cause theres no tick....tick....tick...and they look original. On the other hand, electrics prime the carb well after long standing periods.
The pump will suck air easier than fuel, so seals need to be good, particularly on the filter bowl. If you cant find elements, you can install an inline between the tank & pump. Any regulator should be post electric pump.
I have a box of used pumps if anyone needs one.
When fixing pumps, be sure to clean under the mesh filter in the top of the pump. I had one that was releasing small bits of corrosiony crud which was getting through a tiny (just bigget than the primary main jet) hole in the mesh, and blocking said jet on the Florian.
All good now.
Cheers, Matt.

Best to mount an electric pump as close to the tank as possible (a pump normally can push alot better than it can suck) Also mount the pump on proper rubber isolating mounts to prevent clicking and vibration noises throughout cabin. Solid mounting of these pumps can sometimes prevent them from operating at all as they work on a vibrating principle.

Hey Guys,

Does anyone have part numbers for the needle and seat assembly (with banjo fitting and seals at all. I have remitted my carb and the inlet needle supplied was too short for my nikki carb.
Attached is a photo of my existing one that I wish to replace. I would probably need a float as well please.

generally you only find those parts as part of the carbi kit, Redback.

best to try some local carbi guys, preferably one which has a few old guys who work there as they are often more help and have more knowledge with older vehicles.

or perhaps one of the forum guys have a few bits kicking about. mine are all old used ones which would not be much better.
most float systems work quite well even when old and brass washers are found at car parts and carbi suppliers.
also can use red fibre type washers like this Grab Kit pictured below as dont get effected by fuel.

Good Luck
