Just my two cents worth on the issue if you are keeping the motor stock why would you want to add twin sidies?????????I agree with white sedan get a cam and maybe polish your inlets and raise compression a little.I have been told that by adding the sidies to a stock motor you would over fuel the engine get bore wash and end up with a worn and tired motor in the end.Maybe if you do what white sedan said you may just get away with it.

Okay fellers I am just a simple printer but don't you think adding a weber to an A12 that is not only stock but not in the best of shapes as well a waste of time.I would think that it would be better to get a cam,raise the compression and all the other things that we do to these legendary little A series engines to make the weber worth while???Again I could be wrong as I am a printer and not a mechanic.

Yes I agree you would need the GX head to make it work or get new intake manifold to suit your A12.

I think that you would have to work the motor slightly for the 32/36 to be worth your while.Why don't you just try and source a good second hand carb from a champ?

okay fellers I am staying away from the 38mm chokes and thank you for all the help it is greatly appreciated.Now what else can I do to my A15 motor to get more bang out of it?????????

okay I'm going to stick to the 32s but what else can I do to this motor to get more bang out of it but at the same time I wil be using it as a daily drive.

Oh sorry i forgot to mention that it has a cam I'm in Zimbabwe and the cam I have is what we call a stage 2 cam don't have the specs on it though.Oh one other thing is that we don't have anyone with a dyno here believe it or not.What else could I do to this motor to make it faster but still reasonably reliable.I don't want to bore it out as the bore is still in very good condition.

Hey there fellers just a quick question I know it may be a stupid one but here goes.I have an A15 that I am building and this is what I have done.I have a 4-1 branch the head has been very lightly ported and skimmed down to make 11.1 compression the fly wheel and crank have been lightened as well.I have also done the e15 electronic dizzy swap.The question I have is have I done enough to this motor to make using 38mm chokes worth while or shall I just stick to the 32mm ones.Oh the carburetors are 40DCOE32 Weber.Please fellers I am no mechanic so all your help is much appreciated.

Thanks Immy

That clears up why I never got any response from him.Do you have any idea when he'll be back????

Thanks pepper

I have tried 120fly but he never seems to reply me or maybe he isn't getting my mail.If someone could please help with a number or any other means of contacting him that would be great.
