This is made from a Holley float bowl and an off-shelf  McNeilly
leaning block. It is integrated into the 2 rotor existing slide
throttle kit for p-ports so it is real reasonable for a carb. Less
than $400.

I came to the conclusion that the fuel orifices  don't have to be in
the metal carb body. As long as they are located near the float level
and up stream from the throttle it will work. In this case rubber
hose is used to connect the fuel orifices with the float bowl and
mixture control. Very simple and very low cost.

Since it is a side draft it is lower profile than the Holley 2
barrel. It is also more streamlined internally so it will generate
more power. Just a straight shot into the engine.

No choke necessary as you start it full rich. No accelerator pump as
you move the throttle slowly and at full rich. The blue lever hanging
down is the mixture control.

This is a low profile set up so it will fit in almost every side by
side airplane. We have some  new water pump modes to give room for
the laid back intake tubes.

It is conceivable and simple enough one  could make their  own.

Paul,

Wondered if you are going to build one? The tubes located on the
runners and the float bowl level have to be in alignment? That would
dictate where the bowl would have to be located? Thanks for any
input.

Joe Berki

Yes. Exactly and this is located properly.

I can make it in a day. I have all the parts.

I am looking for somebody that has a p-port engine ready to run with
gear box and prop to test it.


Anybody need a manifold and carb for a p-port engine?


I have a running RX8 P-port engine but I would need to build a test
stand and take the gear box and prop off the RV4.

I can use the wall outlet CDI for the ignition.

Paul,

I will let you know when I am close to starting the engine.
I have been working on the intake with fuel injection, wiring for engine stuff, arduino engine monitor wireless to an I pad, and the fuel system, just installed fuel shut off valve operated from cockpit.  I also am re doing the rad/oilcooler mount to hinge downward and provide better access to the fuel system so I can change fuel filter element.
I have the EC4 mounted on the cockpit side of the firewall and am wiring it with controls on the throttle handle.  The plan was to replace the EC4 with an EC3 when it came time to fly.  I still like the carb idea.

OK Joe.
