Hi guys

I am in the process of needing to overhaul my carb for my ute.
I fitted an A15 a few years back and when I went to fit it the carb was stuffed so I re used the one from my A12.
It worked fine for a few years but now that one is in the need of some attention.
I don't still have the old carb to compare it to and only have A12 carbs in my spares.
I was hoping to get hold of an A15 carb and re kit it but I thought I would check first and see what the difference (if any) is between an A15 and A12 carb.
Do they have different jets or is the bowl size different too?
Is it possible to use A15 jets in the A12 carb?
Are there any markings on the 2 carbs to identify which is which?

Any help would be hugely appreciated, If I am going to the trouble of having a carb recond I would prefer I did it with the right size carb to feed my engine.
It is mildly worked with quite a bit of headwork, cam, headers and lightened flywheel but nothing too outrageous.

I would love to go with Sidies but there aren't many available and funds wont quite stretch that far at this point in time.

A15 has vacuum secondary, bigger 22 and 26 chokes/venturis, bigger 100 and 145 jets, different air bleed jets too.
A12 carb isnt ideal as the smaller carb will tend to wear your engine in time due to washing the bores with a rich mixture from choke/venturi restriction.
I have a spare A15 carb for sale.
I also rekit factory carbs for A-series.

Cool thanks for your valuable information, how much do you want for the A15 carb also how much extra would you charge me to rekit it?

Cheers
