Hi Paul,
You where right the Revmaster is an Edelbrock carb. I can get these
for $221.00 US each. I am waiting to get a price for the postage of
these units. Its very simple to modify the float bowl. in the
modification I will make the base hold both carbs. By making the left
and right you get a great installation and only have one leaning
valve.

It would be too small for the rotary but maybe all right for the
six cylinder 110 HP Jabiru if you used two.
Max rating on these is about 50 HP each.

The cross sectional area is what counts. They are about 40 mm which is
1250 square mm.

A Le Mans engine runner would be about 1.875" or 48 mm in diameter.
The area would be 1800 square mm or about 50% more area and HP each carb.

Hi Paul,
I was running one of these on my Jabiru 120hp engine. The original Bing
carbi would only rev to to 3250 rpm. straight and level. With the
Revmaster 40 mm I was getting 3500 rpm with the same propeller. The last
30 % of throttle did nothing as it would get full power without having
it wide open.

Just one? Wow something not adding up here.
Those Edelbrock carbs are designed for all those off road quads,
bikes and small motor cycles with about 50 HP. Did you monitor the
manifold pressure in both cases? How big was the Bing? Did the Bing
have a butterfly valve in addition to the slide? Could be the Bing piston
was not moving up as far as it should or the piston spring
was too stiff.

BTW here is the mixture monitor I was talking about.
