How to check ignition timing on cranking

Still battling cold start flooding problem (88 900S 16V non-turbo 318k). Anders was kind enough to suggest that injector opening times may be out of whack but I don't have ready access to the instrumentation necessary to test. It also violates the KISS rule (Keep It Simple, Stupid), so I've been considering other sources of flooding condition.
Bentley says that, on startup, ignition timing is locked at 5 degr BTDC, holds there til rpms >700, shifts to fixed 14 degr until throttle is opened. EZK takes over after that.
It occurs to me that incorrect timing on cold-crank could cause ignition failure, hence flooding. The question is how to determine timing advance under cranking (non-starting) conditions. I'm certain that if I left her out in the driveway over a cold and snowy Wisconsin night I could arrive at a non-starting condition and do the check, but then I'm out of a ride and I'll have to push her back into the garage to warm up if I need it to start. Alternatively, I could disconnect wires to plugs 2-4 and check timing on crank, but I worry that I'll do more damage than good.
Any suggestions? TIA
