Hitachi B210 carb jets?

[asandberg6]

Hello, first post and a little off topic. I swapped my 1996 Metro to a Datsun 1200 carb. It runs very well and ive been commuting in it for two weeks. The plugs are showing a lean and i would like to re-jet it. Can anyone help me find some jets that will fit?

Are you sure? Carburetors simply mix fuel in proportion to the air passing through it. A larger engine shouldn't need more or less. To the carburetor a larger engine is the same as a smaller displacement revving much higher.

 

I would check that the jets are not restricted with a small bit of debris or dirt which would make them in effect smaller. While they are out have a look at the size stamped on them and record this. If you go to Amazon you can buy a range of carburetor jets (for under $15) for Webers or motorcycles for fine tuning the mixture.  For example if you have a 100 jet, get a 90 to 110 set and you can go richer or leaner.

 

 

These are for Mikuni and range from 88-128 but again this is just an example. I think most Japanese jets are the same thread. For my R1 carburetors I bought smaller than needed and selected a drill size that was correct and drilled them out to suit. I did have a wide band so perfect mixtures were possible unlike reading the plugs.

Ordered these jets and they fit. Installed a #100 in the primary side as the original was unmarked and i did not want to go any leaner. Will drive it to work tomorrow and see how it burns.
