Hi guys,

Just yesterday replaced my solex 1B2 into 2B4, it runs, but none of vacuum pipes are connected, sooo no need to explain how it idles

So, does any body have photos, some drawings how to connect?

Thank you!

this one looks help full, just doubt about TWO instead on ONE pipes from distributor... but have to check it, maybe am wrong, but 90% sure that there is only one now...

In that case you only have the connection for vacuum timing that makes the timing earlier i think.
You can see that from where the connection at your vacuummembrane is.

Connected everything like in picture...but it idles shitty...

most of the problem is that i have two hoses coming out of intake manifold... dont know where to put it...?
And that my distriburot has one "exit", so probably that makes also abit wrong.

PLUS: when i put my hand ON carb , it idles normal, but when i take it of it starts to try to go off... and where is fuel supply screw, or there is none?
