Carburetor well tubes and how they function-Rick's Shop

[@7080nik]

Great video explaining the basic function and emulsification process!

[@Adrenacyde]

This helped A LOT, thank you! The whiteboard diagram made it easy to understand.

Rick, this video and your videos on the summit carb are extremely useful and well put together. Thank you for posting.

the venturi effect would pull 4 times the fuel at double engine speed. the bleed air balances this down to double fuel at double speed.

Thanks for helping me understand one more thing about carbs.!

[@turboman8522]

best explanation thanks,better if also explained why we can adapt a bigger carby by tuning the air bleeds and emulsion holes

Jetting size for a L28 engine an emotion tubes to use to get performance

[@COLLAR01]

Wow great info

[@chrisspain7776]

I have a Weber which is running too lean when I am at full throttle, high engine speed, but too rich at light throttle. I just can seem to get enough fuel at the top end, unless I do something radical like block off the air jet, then of course its too rich at low speeds.

[@ricksshop]

Go down in idle jet size to fix the rich low speed issue, and up in main jet size to fix the lean condition.

[@chrisspain7776]

@@ricksshop Tried lower idle jets and it doesnt work. I think the fuel is coming from the main orifice.

[@ricksshop]

@@chrisspain7776 check the air bleeds to make sure they are open, and float level...

One more mystery solved..... .....or, ok, I won't mess with em. 😁

[@MattsRageFitGarage]

Have you ever removed the well tubes from a Holley metering block like the one shown? not quite sure how to get them out for cleaning without totally ruining them.

[@ricksshop]

Yes I have. Once you get the plug out of the top. You can drill and tap a shallow hole in the top of the tube (don't break through into the fuel passage) and suck it out with a screw and spacer

[@MattsRageFitGarage]

@@ricksshop I drilled and tapped the well tubes out of two carbs to 6-32 and threaded a screw into them. My home made vise grip slide hammer takes them out effortlessly damage free. Thanks!

nice vid.

[@carlodonnell146]

Is a well tube the same as an emulsification tube?

[@ricksshop]

Yes...
