Electronic Distributor For 4k Engine

[Tham]

I have just bought a Nippondenso electronic

distributor from one of the salvage yards, with

a built-in ignitor.

 

The vacuum advance diaphragm on this unit is

a two-stage type, with two ports, one on top of

the other. The one on the stock points distributor

of course has just one port for direct connection to the

carburetor's vacuum inlet.

 

The salvage yard owner gave me a T-joint to connect

the single hose from the carb to both ports of this

new vacuum advance. Alternatively, he told me that

those plastic/metal splitters for hoses of aquarium air

pumps could be used. I wonder if this is the correct

method ? My usual mechanic, as well as a car wireman,

told me that only the lower port should be used and the

upper one left unused.

 

It also comes with what I think is a vacuum delay valve,

very similar to that show in this pic :

Which port should this go to, and which side faces the

which ? Or can this be left out ?

 

Thanks to the very informative users in this great forum.

Suck and blow on it, You will soon find out which way the vacuum goes..

the one fathest out is the advance, the inner one goes to the manifold for the retard

Thank you, Medicine Man and Mikey's Toy.

 

The vacuum diaphragm on my electronic distributor looks very much like this :

The one farthest out is the advance, the inner one goes to the manifold for the retard

 

 

Does that mean I should connect the hose only to the outer one and leave the inner one unused ?

Had one of those and used both ports as when we tested it, it gave the most advance on my engine.

hi tham.. how have u been....

 

may i know where did ya get the

 

Nippondenso electronic distributor??

 

How much did it cost??

 

thanks man....

[Tham]

From Soon Choi, Cheras, as mentioned in

my earlier posts.

 

Cost $180.

Hi again....

 

U mention that is was internally ignited....

 

Does that mean we dun need the coil....

Internal ignitor type:

Nice photographs.

 

The one I purchased looked very similar, even

the two-stage vacuum diaphragm.

 

Mine had serial number 19050-13130.

Nice photographs.

 

 

Thank you.

 

I bought mine from U-Pull-It, in South Australia for $28.50.

 

It had a cap on it so the bloke didn't realise it was electronic, I guess.

 

Bargain!!

 

It had a 2 stage vacuum advance too, with a T connector, so I just dropped it in and it worked.

Wow. That is a real bargain. Just M$75 here,

less than half of what I paid for it. The salvage

yard owner threw in an old electronic coil made by

Hanshin of Japan though.

 

I'm still using my old points coil with a resistor, as

the above coil looks really old. Wonder

if the performance will be better with

the electronic coil.

 

It had a 2 stage vacuum advance too, with

a T connector, so I just dropped it in and it

worked.

 

Did you connect the T-connector direct to both ports ?

 

Did it come with a vacuum delay advance like the one

shown in my link above, and if so, how did you connect it ?

 

Thanks.

It didn't come with a delay advance, but I removed it from a 4k engine so it could have been installed by anyone, yes the T connector just splits the vacuum from the manifold to both ports on the advance, and I just connected the wires to my existing coil and ballast resistor setup.

 

As I said this is the way I found it set up on the 4K in the yard and I put it on mine the same, but it is not neccessarily the correct way?

 

Good luck.
