Hi Richard, just
wanted to drop a note

setup and sale. We had
the car at Mid Ohio this

Wow, what a difference. I could
never get the Weber carbs perfect. I can now enjoy
the car without messing around with the Weberís. No
more rich idle, no more boiling over at shut off, no
more popping, no more debris issues. The car has a
whole different feel, from idle to wide open it is
smooth with a noticeable horsepower increase. PMO
was very accommodating to my individual needs and
was easy to do business with. Thanks Richard for a

Richard Broadbent, Edwardsburg, MI, April 2005
I think your carburetors are much
better than Weberís. Youíve cleaned up the air flow
beautifully. All the right angle bends are out of the
idle circuits. Your carbs are pieces of jewelry. You
are doing everything right!
Tom Bosworth, Ex-Ford Carburetor Specialist, Oro

Bob Glacken, Sparta, NJ, December 2004
We recently built
two racing engines with your 50mm PMO carbs.
The carbs dialed in really quickly and easily.
Both engines ran great! The 3.6 put out close
to 360 horsepower and the 3.4 close to 340
horsepower. These values are considerably
better than what a racing electronic fuel injected
engine achieved that we recently dynoed.
Peter, PBR Restorations, Crockett, CA, December 2004
The minute we put the PMO's on it was like a
different car. Nobody knows why a brand new
set of Webers didn't work, but the PMO's made all
the difference. I really appreciate it.
Christian Van Fleet, Long Beach,
CA, September 2004
I have just
completed a Porsche 2.7 conversion using PMO's.
Though the motor has only 700 miles on it and hasn't
been pushed at all, I thought I'd offer these
comments for anyone considering carburetor options.
My car was a 73.5
in its former incarnation...the first Porsche
application of CIS. As several Rennlist members are
only too aware, I had a lot of CIS issues, though
after five years of fussing the car finally ran
After searching for Webers for a while, I finally
decided to spring for PMOs. This was the result of
my inability to find Webers in decent condition and
an analysis of what they would likely really cost
after rebuild etc. PMO took our specs (9.5 CR, Elgin
cams, etc) and delivered carburetors the following
day. As best I can tell, NO further adjustment/jet
changes (after initial set-up) will be needed.
Performance is excellent, there are no flat spots,
power seems spot on, throttle response is
incredible, and the motor is smooth as silk from 2k
to as high as I've dared go so far. Really quite incredible. My mechanic says they
have already saved me the $500 or so it could easily
have taken to get some rebuilt Webers running
correctly. Usual disclaimers apply...just a very

I use your PMO 50s on a 1973 911

Carbs are fantastic!
Throttle response is phenomenal. Car is quick;

me as a reference.
Chuck Ehrenberg, Alston, MA, May 2004
The kits we have purchased have
been set up perfectly. Every set we have sold
has been met with extreme happiness by our
customers. They clearly work much better than the
old Webers we were used to. Thanks again for
the great products.
Rockaway, NJ, February 2004
Our 3.4 with the 50 PMO's makes
350 HP at the rear wheels! Easily beats out
cars with their $20,000 injection systems. At
the 2004 PCA race at Road Atlanta we also beat
factory 3.8 RSR race cars with our 3.4. With
the PMO 46s on our 2 litre cars we get more power
and much better drivability than the Weber 46s.
Scott at Auto Associates, Canton, CT, April 2004
The 2.5 Litre with 50 PMOs put out
308 HP on the dyno. Dave White got the pole and took
first in class recently at Daytona with this engine

Just wanted to thank for you for
the great PMO carbs that I recently installed in my
1968 911S. The carbs are really easy to setup and
balance, and very fuel efficient. I used to do 150
miles on 50 Liter on my old Weber, and now it's 250
miles on the PMO. Very smooth idling at 900rpm, and
acceleration without hesitation. It's a dream come
Jeff Chua, Singapore, November 2003.
Excellent dyno results from a
2.0 race motor; 20 more horsepower between 7,000-

difference especially at a track like Daytona. It
responded well to the mixture screws, and has a nice
idle. We were tickled pink with the PMOs, very

Webers take too much time and

can bolt them on and get the horsepower and drivability
we're looking for... without the exhaustive labor.

328 horsepower out of a 2.5
liter! You'd swear it is electronic fuel injection,
it's so smooth. We install a lot of EFI systems, but
this motor is optimized. I recommend your
carburetors to everyone. The customer wouldn't give
up those carburetors for anything.
Jarvis Tech, Ft. Lauderdale, FL, September, 2003
