Тема для глупых вопросов

[Максимка]

Вот, что пишут американские авиаторы:

If the engine has been sitting a long time, it might be a good idea to pre-oil it as Lycoming recommends before starting a new, overhauled or rebuilt engine. This can be done by removing the spark plugs and spinning the prop either by hand or with the starter until oil pressure is indicated.

Хотя это всего лишь рекомендация.
