Subject: | Carb issues for the corvair |
Fellow Pieter's:
I am interested to hear what carburetors are use on the corvair conversion. It
appears the NA-S3B Stromberg has been mention but having difficulties finding
a good one even on E-Bay. Are there other carbs being utilized more often than
others? Just looking for answers before I start my search....

Ken,
This quote from William Wynne's site:
-There are four different carburetors that dominate the field of flying
Corvairs. These are divided among two applications: gravity feed fuel
systems (most high wing airplanes and low wing airplanes with header tanks)
and pressure fuel systems (mostly seen in low wing airplanes without header
tanks). If you are using a gravity feed fuel system, you can use any of the
four popular carburetors. These carbs are the Ellison EFS-3A, Marvel
Schebler MA3-SPA, Stromberg NAS-3, and Monnett Aero-Carb. If you have a
pressure fuel system, like a 601XL or a KR-2 without a header tank, then
you should be using an EFS-3A or an MA3-SPA. The Corvair runs well on all
of these carbs. Bill Clapp's KR-2S has nearly 300 hours on an Aero-Carb.
Mark Langford's and Steve Makish's KRs both run on Ellison EFS-3As. Dave
The Bear's Wagabond and the Skycoupe both fly on Strombergs. Our 601 and
the Cleanex both have MA3s.
Ellison Fluid Systems sells the EFS-3A. And the Monnett family is the only
place to get an Aero-Carb. Either of these carbs fit on a single model of
our CNC stainless intake manifold. Alternatively, the Stromberg and MA3
both fit on a slightly different manifold we make. All of the carburetors
except the MA3 require a primer. We weld a single primer port in the up
tube on the right hand side of the intake manifold. This is common practice
on certified engines. The MA3-SPA's accelerator pump makes a primer
unnecessary.-
My comments:
All of the above are either hard to find or expensive (or both).
I choose to go with a Zenith Carburetor as used on the larger VW
conversions.
You can buy them at: http://www.greatplainsas.com/sccarb.html
They call them 1821 carburetors after the VW engine conversion they
represent.
The Zenith designation is # 267 see at:
http://www.zenithfuelsystems.com/updraft_267.htm
It gives me about 2800 RPM static and about 3000 WOT flying
Although I fly most of the time at about 70 Mph which is less than 1/4
throttle (2200 RPM)
I did remove the choke, have a primer on the LH intake manifold a home
made carb heat box.

I use the Zenith on my 1/2 vw and you can't get much simpler than that
carb.

Ken,
The Marvel MA3-SPA shows up periodically on eBay. After watching for
about 3 months, I got one for around $100 (it's been a while, don't
recall the exact price; William jokingly offered me $5 more than I
paid for it sight unseen - I think he prefers it over the other
models he recommends, with perhaps the exception of the Aero-carb,
which he also holds in high regard ). It needs a rebuild, which will
probably run around $350 if I buy the parts & get help from the guy
in our EAA chapter that owns a machine shop.
