Editing Starting fluid (section)

===Four stroke engines===
Starting fluid is sprayed into the engine intake near the air filter, or into the carburetor bore or a spark plug hole of an engine to get added fuel to the combustion cylinder quickly. Using starting fluid to get the engine running faster avoids wear to starters and fatigue to one's arm with pull start engines, especially on rarely used machines. Other uses include cold weather starting, vehicles that run out of fuel and thus require extra time to restore fuel pressure, and sometimes with [[flooded engine]]s. Mechanics sometimes use it to diagnose starting problems by determining whether the spark and ignition system of the vehicle is functioning; if the spark is adequate but the fuel delivery system is not, the engine will run until the starting fluid vapors are consumed.  It is used more often with [[carburetor|carbureted]] engines than with [[fuel injection]] systems.  Caution is required when using starting fluid with [[diesel engines]] that have preheat systems in the intake or glow-plugs installed, as the starting fluid may pre-ignite, leading to engine damage.<ref>{{cite web|title=The immediate engine damage that can result from ether starting fluid use|url=http://www.thetruckstop.us/forum/threads/the-immediate-engine-damage-that-can-result-from-ether-starting-fluid-use.46065/|website=The Truck Stop|accessdate=28 December 2017}}</ref><ref name=WikiHow>{{cite web|title=How to Start a Diesel Truck|url=http://www.wikihow.com/Start-a-Diesel-Truck|work=WikiHow|accessdate=2 January 2014}}</ref>
