the airfilter is on & the weber is ready to be jetted and tuned properly. im thinking around about a 33mm venturi size, if my maths works. im taking it some place local to be jetted tomorrow :)

heres a part list for an A12 hitachi 306 to DCOE weber conversion.

1 x 42mm DCOE weber (this one was free thanks to someone who gave me a complete but old ex rally car 200B with it installed)
1 x Redline Datsun 1200/120Y single DCOE manifold ($230)
1 x Redline linkage kit for DCOE 40mm for Datsun 1200 ($100)
1 x Redline air filter and new metal bits ($40)
2 x nuts (one is a metric 6mm fine and other i dont know)
1 x aftermarket Manual Choke w/ long cable ($30)
1 x aftermarket 5/8" air filter [shown above rocker cover] ($30)
1 x plug to seal the hole which used to run a pipe to the bottom of the old hitachi 306 carb.
1 x small length fuel line hose
1 x box small fuel line clips
1 x datsun 1200 gasket ($20)

engine now sounds a lot racier and will hopefully be heaps more toey when it gets jetted.

It doesn't have the same visual impact as two Webers, but for street duty, when properly tuned [at a lower cost than twins] it will go every bit as good, & it may even provide even better overall performance.

Good on you, let us know how it runs.

got it dyno'd today - cost just over $400 :( wish i knew sum1 with a dyno. they also fixed a few small things and in doing so had to pretty much dismantle it from the manifold so the labour cost was high.

it goes heaps better in all gears. more torque and easier to get to 60-100-140km etc :) good sound as well, sounds like it is much more than just a A12.

the parts he sold me to jet it properly for my A12 were ::

2 x main jet 140
2 x idle jet 45F8

the car's timing was also changed to 12 degrees above BTDC.

on the dyno she created 83hp at 5800rpm then next run 91hp @ 6630rpm.

Linkages came from Unifilter who got them through Redline. Turned out my old man used to race cars with the boss at this unifilter dealer so I got things nicely discounted. I think I was quoted $100 by Redline when I called them one day. Lynx dont make a linkage kit i think. **

im wrong Lynx DO make linkage kits. (a friend of mine bought one for under $50 for his 1600 single DCOE weber)

 Re: 42mm weber installed
I know this is old but Im planning on putting a 40mm weber on my a14, and I reckon I'll have to pay for a new manifold as single weber to A-series dont come up too often.
I was just wondering why the big fancy linkage setup? why not just bolt the stock half-wheel onto the side of the carb and fab a holder for the outer? I know its not recommeded for twins, but for a single it would be easier I reckon.

i had no weber books nor did i know enough to shop around for different linkages at that time. i just ordered the manifold and the single dcoe linkage kit.

i would do the same, use the alfa style dcoe throttle linkage and away you go.
