Title: Carb design on 400
Post by: McCabe-Thiele (Ted) on August 31, 2022, 09:44:31 PM
Whilst restoring my spare set of carbs got me thinking (I know dangerous).
The long brass part that I call the emulsion tube had a series of holes down the sides what do they do?
I assume the fuel supply is restricted by the bottom orifice/jet plus the float level. Is it connected with atomisation perchance?

Yes, the emulsion tube is an atomiser.

Whatever you do Ted don't put 2 emulsion tubes together as one atomises and the next splits that atom, the resultant explosion has to be seen to be believed  :) :)

I can see this topic is going to mushroom out of shape.

But they don't do a very good job of laying the back lawn.

Thanks for the warning Ken I have my Neutron Moderators on standby.

Always mark a pitch out though.

You won't see it twice......'as they stagger blind and burned through the rubble those who survived will envy those who died'.   :o I suggest letting the qualified work on your carbs!  ;)
