A method obtains information for adjusting an adjustable component of a combustion engine drive system of a gardening and/or forestry apparatus. The method includes the steps of: providing a characteristic parameter using a mobile provision device, wherein the characteristic parameter describes a characteristic of an environment of the gardening and/or forestry apparatus; and obtaining the information for adjusting the adjustable component as a function of the provided characteristic parameter.

Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods and gas field development methods are provided. Gas is compressed hydraulically by seawater introduced into vessels and separated from the gas by a water immiscible liquid layer. Tall, possibly vertical helical vessels are used to reach a high compression ratio that lowers the liquefaction temperature. Cooling units are used to liquefy the compressed gas, possibly by a coolant which is itself pressurized by a similar mechanism. The coolant may be selected to be liquefied under surrounding seawater temperatures. The seawater which is used to pressurize the gas may be used after evacuation from the vessels to pressurize intrastratal gas in the production stages and broaden the gas field development.

A carburetor for an internal combustion engine includes a body having an air inlet opening portion, an air outlet opening portion, and a throat portion extending therebetween. A fuel reservoir is in fluid communication with the throat portion. A slide assembly is movably disposed in the body for movement across the throat portion. The slide assembly includes a metering rod extending across the throat portion and into the fuel reservoir. An electrically operable actuator, when operated, adjusts an axial position of the metering rod relative to the fuel reservoir.
