Hi David,

or else can i use A 12 Jet Sizes for this A14 carburetor

primary, A12: 96
secondary, A12: 150

Please suggest best thing according to your knowledge

Thanking you

I would start with the A14 jets.

Jets are first selected for the size of the venturis.

Ok then i will proceed with the A 14 jets

Thank you

Hi DD,

My car is now running well because of your help.Thank you very much david.

Yesterday I replaced the main jets of carb. Now its pulling well without any misses. I found only 104 size for primary and 145 size jets with carburetor repair kits in local market. Any way its running well with 145 size for secondary.

The old jet sizes was 87 for primary and 97 for secondary

and now I am going to check fuel consumption

Thank you again
Indika

glad to hear it is an improvement.

wow those old jets were very small. Check the size of the air bleeds, because they are like very small to match (otherwise it probably would not have run at all).

Jets and air bleeds go together.

By the way, repair kits in USA do not include jets.

Hi dd,

The repair kit was Datsun sunny B210 suitable model (that's why secondary jet size was 145) .I used jets only from that kit because air bleeds not matching to my carb.(Totaly different)
