Yeah, still want to advance timing. Really only need 3 speed settings,
Idle -- does not matter really. Then full power and cruise speed are
the two that matter. I am having all sports of grief with Fuel Tech
having spent $4000 AUD on it. It is good but as always complicated. A
carby plus simple ignition will do. The Rotec carby for $800 is so
simple and runs on 5 PSI. Trigger wheel would be a reasonably simple
change.
