Carb Nomenclature With Pictures
« on: April 27, 2020, 02:10:24 AM »
OK, I'm bored at work so I'm going to see if I have my nomenclature correct and post my early-learning photoshop pictures if Cliff doesn't mind.  Let me know what I got wrong if anything.  Pretty sure it won't hurt book sales......

Lower Idle Air Bleeds.  I know these images and colors are hard on your eyes, but bear with me!

Little holes in the top of the airhorn that should be left open.  They are the ends of tubes that go into the secondary fuel passages.  Do we drill these out at all??

THANK YOU WideTrack. Assuming everything you posted is correct, this REALLY helps me gain confidence. There are so many different terms floating about a solid definition with pictures is a great help.

Buyer beware, Miner!  Pretty sure it's correct though!  It's from a late 70's Buick carb.

Yeah, I'm a cautious and skeptical fellow, but it does help that your determinations are in line with the ones I made independently from Cliff's book. I'm more of a late 70's & early 80's truck carb sort of dude. Nice to see they didn't deviate drastically with Buick.

But of course somebody else will need to come along with their own photos and identifiers to help the earlier guys with different styles.

Yeah, I have enough trouble just trying to figure out one make and style.  My car originally had a Carter on it.  I have new respect for carburetor engineers.  They built one heck of a Rube Goldberg device!

These are emulsion tubes (air bleeds)  for the secondaries, they're critical for fuel atomization when those beer can secondaries open. Pg. 106 of the Bible recommends .036". I always check just to make sure.

Thanks, Rule!  I was a little confused about whether to drill THAT part of the "tube" as the restriction, or the bottom end of the tube, or both.  Let me look at page 106 again. 

OK, here's a question for you.  I wrote this down in my notes from the bible as recommended sizes for "recipe 2": 

"Secondary Tube restriction: .036
Main Well Bleed Tube: .036"

Those tubes that hook up to the little holes in the top of the airhorn are the "secondary tubes" in my notes.  They currently measure .024 at the BOTTOM. 

Should I drill them out to .036 at the bottom of the tube AND at the top of the air horn?

Thanks in advance.

Here's a shot of my carb-rebuilding station, just like Professor Ruggles teaches us.  I blasted it with soda so any passages aren't clogged by glass beads or sand.  Just ordered my rebuild kit from Cliff today.

I would stick with Cliffs recommendations on the recipe. The small bleed hole would make for a rich condition with the recipe recommended secondary rods. Air bleeds are like a cracked soda straw, the bigger the crack the less soda. Good luck.
