I am still looking at carburetors for my 13b.
I haven't decided to ditch the EFI yet, as I have the maps set up now and it
seems to be producing good power, and runs smoothly. After talking
to George Graham, and seeing that Ron Gowan also had a carb on a 13b, (as well
as Finn and I believe the gentleman who had a Coot amphibian), it would seem
that there are some success stories with a rotary and a carb.
Now that we are talking about PM
alternators, with around 35 amps, it would seem that if I had a carburetor
instead of EFI, my electrical current needs would be considerably less. (No
injectors to fire, no high pressure fuel pumps, etc). I could also
eliminate the need for a fuel return line to sump tank, handheld ECU
programmer, etc.
Of course there are
downsides to carburetors as well, such as the need to provide inflight leaning
of the mixture and carb heat. The carb heat is the easy part. (not very
far from the exhaust). The real challenge would be providing for inflight
leaning of the mixture. If anyone has seen a succesful modification of a
Weber carb for inflight leaning, I would appreciate any info you might
have? Thanks in advance for any and all replies. Paul
