Lets communicate more effectively

In order to communicate effectivly, we need to speak the same language.  It is hard to communicate with terms like "the thing that goes up and down that looks like a nail," or "the part with two fingers and three holes."  I actually hear this sort of description often.  This description was actually pulled from a recent e-mail....."Those Vacuum control thingamigige things"

There are three main parts to the tripower carbs.  The "top" is known as the airhorn.  The "center section" is the floatbowl.  The "bottom" is not the baseplate; it is the throttlebody.  If you deal with fuel injection, you know the term "throttlebody."  It is much more descriptive.

These are not pictures of actual tripower carbs, but the labels are correct.  For your information, the throtlebody in the illustration is likely from a 59 to 67 Pontiac 2 bbl.  Note the choke cup is mounted on the throttlebody, unlike a center tripower carb.

The airhorn in the illustraton below should resemble your tripower center carb. However, the end carbs have no power piston, choke parts (of course,) or power valve.

The end carb throttlebodies will have no idle circuits..so no idle mixture needles or idle compensation channel (see pics below.)

In the illustrations to follow, the internal parts are labeled. School is in session.  Use these terms when you call or e-mail me and you get an "A."  And, I will appreciate it.
