Thanks.
We will be running a vortex electronic ignition that will talk to the tps and power-jets, so the mc28 carbs may be the go.
As for boring out the carbs, we can possibly bore up to the needle-jet from each side and then hand finish the rest.
What about the mc28's pgm system which apparently "opens solenoids at appropriate times which in turn control specific air passages into the carbs"(quoting a magazine article here).
Anyone got more info on this carb set-up for MC28's?
Cheers
