KR> Zenith Carbs and source reference

[Dan Heath]

If you want to be really smart and save yourself a lot of money in the long
run, and FLY, you will choose something that has already been proven to
work, no matter what it costs.  Get it wrong just ONE time, and have to do
it over, and you will have lost a lot of flying time, money, and maybe your
plane.

But, if you have unlimited time and resources, please keep us informed of
your progress.

See you at the 2010 - KR Gathering in Richmond, Ky - I39
There is a time for building and a time for FLYING and the time for Flying
has begun.

However when it comes to 
carburetors for the corvair there is some questions that need answered.

Holly has a great book out on carburetors, intake manifolds, theory  and 
the calculations for all. i would make it a part of your recommended 
reading.

Ok, we all know what Cam, crank and setup to use for our corvairs. Mark 
Langford and William Wynne have gone through a lot of trouble doing the 
R&D for us and I wish to thank them. However when it comes to 
carburetors for the corvair there is some questions that need answered. 
The certified carbs are very expensive and hard to find while Harley CVO 
carbs and Zenith carbs are available and reasonable.  So I'm looking 
hard at the Zenith Carb and what the numbers really mean. On forums the 
Zenith 1821 carb is being called a number 68 and 267 Here is a chart to 
show you the size engines for these carbs. Just click on the updraft 
carb 68 or 267 to see the specs.

Now here is a chart to see how these carburetor numbers are related:

The numbers you are after is 13922, 14992, 14995 and 14998 depending on 
your engine setup and size. These updraft carbs are dirt simple and can 
be adjusted easily to run your corvair. If you live in the woods like I 
do then here is the cross reference chart to get a carb from a tractor 
dealer:

Now here is a dealer like www.greatplains.com 
 that carries Zenith carbs for aircraft:

And a small article on  carbs that contains good information:

These updraft carburetors don't like ram air or high pressure and need 
to be setup with available carb heat for flight safety.

Here is the cheapest I found them:

I hope this helps out in trying to find a carburetor for your project.
