Carb cooling fluid, ehhh

[Jens]

as some might know, iam struggling with my hawk.

Wass checking the carbs for leaks, when i saw this strange thing, never see it before, but also my first v-twin.

If you take out the carbs, turn em on the head. Under them there goes a water line, from on carb to the other, from the line there goes a pipe to the waterpump i think it is.

I removed the line to check it, when i blow into it. the front one, i can hear air comming out, i think thats how i should work. when i do the same to the read one, but no air comes out, looks like its blocked !

So as i can see water goes in on the rear on the carbs, but dont goes out again ?

Is this right ? also are the carbs affected by the water cooling ? the one that are blocked, is that by factory or a fail ?

thx

I would say it's by fail from what you say.
Water (hot) goes in through the rear pipe to the carb, flows through the short pipe to the front carb and then exits via the front pipe.
I don't know if there are any non-return valves, I've never blown down one before.
