All IMHO:

The pilot circuit on Amal Concentric, Amal MK2, and the Mikunis similar to the Amal MK2 will all drain back to the bowl over time with the engine not running. Without tickling or the enricher, it is tough to get the pilot circuit refilled when kicking. So, needing to add fuel via the tickler or enricher after several minutes is not abnormal. However, it is easy to overdo it with a warm engine and then be flooded in which case throttle is needed to add air to clear the flood.

Basically, assuming a good ignition system and properly setup carb(s), none of them need any throttle when cold or hot. Adding throttle (less than 1/4 throttle) adds air but does adds little to no fuel - thus making a lean, hard to start mixture. This is true cold or hot.

On the other hand, an e-started will normally spin a warm engine fast enough to not need the tickler/enricher.
