As requested by Simon...

Should chuck it in the FAQ. :)

hey look.....my hand...:)

 

thanks justin :)

The distributor I bought for my 4K from

the salvage yard here was also marked "5K".

 

The connector was identical. It also had

a two-stage vacuum advance pump.

I think it was mentioned in the other thread, but how much are these worth? $120 odd? or was that new? :lmao:

about $80 - $120 second hand....

hi!!

i have the same distributor with the two-stage vacuum advance pump and i don't know how i connect it???(the two-stage vacuum advance pump)???? :monkey:

You can use a plastic T-connector, which

the salvage yard owner can probably give

you, and connect the single hose from your

carburetor's vacuum inlet to both outlets

on the vacuum diaphragms.

 

Some say that the outer one is for advance,

while the inner one to supposed to go to the

manifold for retard, while others say both ports

are for advance - one giving advance at low to

moderate engine speeds, while the other gives

a bit more advance at very high RPMs. I guess this

depends on the diaphragm's design and engine

application.

 

In my case, both appeared to be for advance, with

the outer one giving more advance than the inner.

I used one of those metal splitters found in aquarium

pumps, which had shutoff taps, as I wanted to

experiment shutting off each hose in turn to see

what difference it made. If you do not have the T-connector,

you can of course use these splitters and open up both

outlets permanently. The vacuum hoses fit them exactly.

If you cannot get metal ones, normal plastic ones can be

used, which was what I used at first, and appear to be

able to withstand the engine heat.

 

You can read my other thread "Electronic Distributor

for 4K Engine" .

Seems there are some script errors with the

pics you posted, can't see them.

 

I'm not familar with the extra vacuum inlets on

other carbs. Maybe the others here can help.

 

According to Mikey's Toy on the other post,

he mentioned that the outer diaphragm port

goes to the standard inlet just above the

carb's butterfly for advance, and the inner one

goes to the intake manifold port for retard.
