''Are there any tricks to cranking and priming an inverted engine? ''
Just be sure not to overprime, and flood the glow plug and/or hydraulically lock, and bend the crank. If all else fails, turn the airframe over, and start so that the engine is in the upright position.

If I remember correctly it is the two cycles that get cranky starting in an inverted position, the 4 stroke engines with their valve systems are somewhat protected against hydraulic lock and flooded glow plugs.
