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

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 Indika

That is the thing , my b210 used to give me 18+ on long run but b310 gave me about 14 to 15 max so far,but are designed for best fuel economy on standard jetting

thanks

The fuel consumption is 13 kmp / l in long distance.

The jets are for a specific carburetor perhaps it says 1978 B210 with A12 engine. The kit label/box should be very specific. If it is not specifically labeled, then do not use the jets unless you confirm which jets the carburetor needs, although they can use the same gaskets and other parts.

The rest of the kit works with many variations of the carburetor -- most of which are incompatible with those jets.

Jets and venturis are matched. So putting jets for 20/26 venturi DCH306 into a 22/27 venturi DCH306 will be very incorrect. Minor variations are for fine tuning, but major changes are bad.

Hi Indika

Ok then you are running standard size jets, so what is the average fuel consumption now ?

thanks

Hi DD,

What is the reason for it why you saying that "Do not use Kit Jets" ? In sri lanka repair kits included jets also (made by japan)

Actually we cannot find the Original Jets the reason is earlier owners of the vehicle removed the original jets (sometimes we can find the original jets with whole carburetors which are selling for parts)


Sumith ,

I couldn't find any place for separate original Jets in sri lanka sometimes you can find same model carb with original jets @ Panchikawatte

Do not use any jet that come with a kit! Undoubtedly they will be the wrong ones!

There are dozens of different carburetors DCH306 carburetors, all with different jetting. The original jetting is specific to the exact carburetor. Changing the jetting drastically WILL NOT WORK correctly.


Jets DO NOT WEAR OUT and do not almost never need replacing. When we rebuild carburetors here (or in a commercial shop) we do not replace the jets.
