   I have run a Weber on my coot now for 1300 hrs, I used a 51 mm DCOE
side draft for about 1000 hrs but switched to a 48 DCOE, they also
make a 55 mm DCOE and the best place to get Weber's is at Performance
part warehouse in New York.
  I switched to the 48 as it runs very smooth at the bottom end
compared to the 51 but I did lose some power on the top end but I do
a lot of slow speed water taxiing so its a tradeoff I will except.
   Also for leaning I use a controllable air ram that creates a
pressure difference between the float bowl and the Venturi thus
leaning the fuel mixture.
  I am with you on the simple thing, just hook up a fuel line and a
throttle cable and go fly, if you need jetting info I can give you
the jet numbers to put it dead nuts on.
  I have thought about playing with injection but I will use a Weber
as a throttle body so the if something goes wrong with the injection
I can just flip a switch to the Weber fuel pump and keep flying on
the Weber and worry about fixing the injection I get home or whenever
I get around to it.

Ken, would you mind detailing how you modified the carb with the controllable 
air ram? Do you have any pictures?
