Breather pipe

Can anyone confirm where the breather pipe should go on my 1700 twin carb ?

 

Into the top of your air filter box.. google " itinerant aircooled solex" for those two without tubes on the right side air duct and where they go

 

Here is mine going into the top of the air filter but mine is a 2.0lt so not sure if it’s different

 

I seem to have two inlets under the air filter as in the second picture

 

Not those, they are something else entirely. There should be an equivalent to the one pictured above on your steel air filter housing.

 

Oh yes, I see in the picture, where do they go then ?

 

One of those two pipes close together goes to a vacuum takeoff on a carburettor or one of the inlet manifolds, the other end goes to the vacuum operated hot air feed flap on the inlet to the air filter. So it idles on warm air just like the single carburettor engines do, but draws in cold air for best power at wider throttle opening. .

Basically the same breather diagram as for a centremount carb that came up in discussion on here the other day - just your air filter feeds into the top of two carburettors rather than one.

 

Those two pipe under the arm are connect to a thermostatic cut-off valve inside the arm.

Close, it's connected to a small spur off the central idling system steel pipe underneath the air filter.

 

I don’t seem to have anywhere on the top

 

On the side near the top, like the bigger oil breather one at 4 o'clock.

 

Maybe it's hiding at the back in the centre of the top. Is that a grommet?

 

Have the plastic fuel filter in the engine bay police been along yet.....

I was waiting for that, the garage I use still do that. I moved it in my beetle.

 

One thing at a time.

 

... best copy i could get.. same principle on yours probably for those other two connections

So what should be there to connect the hose?

 

Sorry, no idea, I haven't had that type.

 

Just stick the pipe through
