No, not really.  Unless it were a veritable torrent, the OXS and
computer would balance out a dribble by leaning out the mixture.

Anyway, quit being wimps and drill out those two bolts, the stubs should
come out easier after the heat and vibration of drilling.  Then you can
test the cold start injector.

What is the symptom that leads to the diagnosis that the engine is
running rich all the time?

Have you tested OXS function yet?
