That really varies depending on your fuel.
but on average I think you’d open up your main Needle around 2/3 turns and your Low speed needle (Side) needle Usually stays Flush , I’d always go richer to start off and Lean as Necessary .

stock as in STANDARD (factory) needle settings do not depend on any fuel used... lol
They depend on nothing but the manufacturer's engine design.
No, that's not necessarily true @Deku . The engine's manual will recommend a fuel with a certain percentage of nitro and oil. That's what the stock needle settings are based on. For example, i am breaking in a new Dynamite .21. Needle settings are 3-1/2 out on the HSN and 1-11/2 on the LSN. However, I'm running 30% and even these settings, factory settings, are a bit too lean given the higher %, so I'm running closer to 5 turns out on the HSN.
