Oh yes it can. The advance mechanism is completely independent from electronic ignition. Per John's advice, it should be checked and lubed as long as you're there.
I don't have an Indigo prop but mine is roughly the same diameter and pitch - and with a monthly diving service, clean.
Following a careful timing adjustment I can reach 2600 RPM (direct drive just like yours) although in use I'm usually around 2100~2300.
My recommendations therefore:
- Inspect and lube the centrifugal advance system
- Get the timing set as accurately as you possibly can
- Clean the bottom, shaft and prop
