I once blew the cold start circuit on the
EC2 such that you could not turn it off (no fault of the EC2) – I found
that if I turned the manual mixture all the way lean – it would lean it
enough for the engine to keep running –albeit still way overly rich –
this was with four 460 cc/min injectors, don’t know if it would have worked
with 550 cc/min) .
But, Brian, by experimenting - I
then found that if I turned off one pair or the other of the injectors (with
the cold start function still frozen on) that it would indeed run normally on
two injectors . So Brian, I can attest that will work - been there done
that. Not that’s presuming you have all four injectors approx the
same capacity.

In the event of a primary or secondary
injector failure, the affected injector set can be switched off and the cold
start switch used to richen up the remaining injectors. This as per Tracy's instructions. I
haven't tried this, and hope I never have to in the heat of battle, but there
it is.
