I may be wrong but do not believe that the
Engine Control System that Paul
had supported staged (four injectors) injection.......Again not certain
but I think
his ECS was a "Motec".........

John, I believe the TWM throttle body that Paul got
from Atkins which has injector positions comes with only two injector
positions. This throttle body was available from the distributor (TWM)
in either 2 or 4 injector model. I know from personal experience
that using the 4 injector TW (I had one initially installed) on the 13B made
a more difficult installation - because the two injectors on the
"inside" required you to position the TB a fair distance from the engine
block. So to avoid a lot of manifold work (extending the TB further
away from the block to give room for the two inside injectors), the TB with
only the two injector positions on the outside were most favored for the
aircraft installation. I believe that was the only model sold by
Atkins. I know of one other who also flew with only two
injectors, but there may be more.
Reduce fuel flow whether due to fuel selector
position or defective injector or combination during take off
would certainly be critical. As pointed out, when you lose one rotor
you lose more than 50% of your HP due to 1. Less rpm with only one
rotor ,2. drag of non-power producing rotor.

Does anyone know if and why Paul's engine was configured with one
injector per rotor?
