In my case the original engine was a A14 -1400 cc someone who swapped the engine did not changed the carby so i am running an A12 Motor with Carburetor suitable for A14.

that is why i am using A14 standard jets for this carb (i got DDs advices ) because air bleeds and venture sizes are not compatible with smaller jets (Note : The engine performance is very good now)

and 18+ is very good fuel consumption for your car sumit

Hi Guys

I installed 75 and 105 main jets could't start the car yet since it is having a problem with the starter motor.
I have noticed suddenly i have installed primary slow air bleed wrong, It is different than other jet concept it is having a bigger jet(170) as primary and (100) as secondary is it ? so i re installed them to that spec as per manual 170 main and 100 secondary side

thanks
