you did not think to just take a picture beforehand ?. how about one now with all the pipes you don't know.
distributor one goes to the back of carb and that is almost the most important one.

I bought the car with the carb in the boot. So i couldt not take a photo. I googled the hoses and carb but there are so many photos and diagrams wich is not the same. that is why i want to find out were does the hose from the oneway valve from the brake booster go. ( where on the carb ) and also top left is the choke vacume, i think. where do the vacume come from on that. there is a vacume ball (green one) what supplys the ball with vacume. Please i need help.
Thanks

Ok so the ball is basically supplied by the the one on the brake one way valve.
The choke vacuum should also go to the back of the carb. But these things are very hard to explain without pictures or even know which carb you have. If it is a new carb the choke vacuum should have already been plumbed.
The original carb for that engine would probably have been a pierburg which also changes th vacuum layout.

what happens if you do not attach the vacuum pipe at the back, the one from the distributor one, when I unplug mine I don't see any changes

On partial throttle the car might be surging slightly and if you measure emissions you find that you have lots of unburnt hydro carbons coming out of the exhaust.

Ok then there is a single line for vacuum at the back of the carb. You will take that and tee it to all the places that needs it.
The choke is manual and the second stage is directly plumbed into the carb.

It is a phenomenon called carburettor percolation. Google it.

Spark should be blue. Damn I did not know those things are still around. Used it to tune my rally 510 Datsun SSS Hitachi / SU carbs & later side draught Delorto carbs, with one aided by a vacuum meter (basically a little iron marble in a tube that rise with suction from the carbs to ensure suction level on both carbs are the same. Great memories.
