Hey Mate,
 
Idealy they'd all be the same springs.  You should be able to get some new ones somewhere pretty cheap I'd say.
 
If you plan on getting the car dyno'd (and I stress you should) then I'd get the dude to drill them for you as this way you will have it sorted out perfect rather than guessing as I did.  It will still run with standard jets to get you to the tuners.
 
Are the needles adjustable?  If so put them on the middle setting to get you going.
 
I eneded up ordering a Bogg Bros Manifold as I wanted one without the vacuum and coolant takeoffs.  Here's a couple of pic of their work.  Pretty sexy!
 
Cheers

I am using the M/C from a Datsun 120Y so no booster needed.

Keen to see if pic works : Boggs bros manifold turned up today, what a top lookin bit of kit.. Anyways I still need to drill out main jets but everything else should be sweet... 
Matt75: this will probably all be happening in the next couple of weekends, I have a throttle cable, choke cable, I'll drill jets to 1.6mm, going to initially try the mechanical fuel pump with a regulator, failing that use the one I bought off you, slap it on and go for gold... Do you have any other advice for getting these running well enough for driving around town before dynoing?

Thanks buddy, Ill be back on here about this subject I'm sure :)

Hey Mate,
 
Looks great and sounds pretty good too.  You'll need to fit a return spring on the carbs and on the pedal too for the best results.
 
I used a spring on the carbs where the accelerator cable attaches.
 
Mechanical or electric fuel pump?
 
Try to get them tuned ASAP as if they aren't balanced you may run the risk of running too hot and doing damage.
 
Great stuff.

The bike pumps work great.

I thought of getting a colour tune. Be keen to hear how you go.

Cheers

I should note that I have fuel return hooked up, maybe I should remove this?

For anyone following the thread: If you connect up the fuel return to what looks like brass fuel return nozzle at the front of the carbies, simply goes through to the back to another brass nozzle and your return fuel will go up though the tank under heavy braking and come out there..
