Very fast idle when starting question

Wondering if any engine gurus can shed light on a minor issue I have on my 2000 25hp 2stroke mariner.

The only issue I seem to have is it starts and then idles very fast until its warmed up - when it settles down to a nice tickover speed . (This engine has a thermostat regulating flow of water out of the tell tale until its warm enough)

Only happens from cold , but wondering if anyone knows if there is/was some kind of autochoke fitted on these ?

There doesn't appear to be the same prime lever to puch down the primer like on the manual start engine ( near identical ) I had in the past.

There is something fitted ( on top of the carb with a yellow wire that goes of somewhere ) but the plunger doesn't appear be connected to anything
