What are the 3 conditions that allow the engine to run?
WTATWTA: The four things every engine needs to run
- Ingredient one: Compression. An engine needs compression to run.
- Ingredient two: Air. Air is required to run an engine.
- Ingredient three: Fuel. Fuel and air sort of work hand in hand, as we just discussed.
What does a combustion engine need to run?
Each time the fuel ignites is called the combustion, or power, stroke. Engines need air (namely oxygen) to burn fuel. During the intake stroke, valves open to allow the piston to act like a syringe as it moves downward, drawing in ambient air through the engine’s intake system.
What kind of problems can a small engine have?
These problems can range from a faulty spark plug lead, shorted kill switch or damage to the flywheel. To test and fix possible problems, check out our Small Engine Ignition Systems FAQ. Is your Engine’s Exhaust smoking? If the engine is emitting white or blue smoke, this means your engine is burning oil.
What causes an outboard engine to stop working?
Keep this in mind as you troubleshoot your engine, especially before you go down any rabbit holes, wondering about the ignition system or other problems. Outboards can and do die for other reasons, but it’s nearly always something to do with the fuel. 1. Spark Plugs 2. Dead battery 3. Kill Switch 4. Fuel Problems 5. Carburetor
Why does my gas engine not start properly?
Your fuel needs to be stored in a suitable container and treated with fuel stabilizer to be sure it doesn’t go stale. Stale fuel, dirt, and debris are the most common cause of outdoor power equipment not starting or running properly. If you store equipment with untreated gas in the tank, it can lead to engine damage. Is your oil fresh?
What to do if your small engine won’t start?
Determine why your small engine won’t start by checking your fuel levels, spark plug, carburetor, valve & compression levels and more. Follow along to troubleshoot and learn when it’s best to service your engine.
What are the dangers of running a lean engine?
The problem with this is that a lean mixture is difficult to ignite, and it may increase combustion temperatures to dangerous levels , high enough to melt engine pistons in severe cases. Even when the engine is capable of running lean, the emissions of nitrogen oxides (NO x) can go through the roof.
What happens if there is too little fuel in the engine?
Too little fuel means that the engine is running lean. The problem with this is that a lean mixture is difficult to ignite, and it may increase combustion temperatures to dangerous levels , high enough to melt engine pistons in severe cases.

What causes a lawn mower engine to run lean?
Air that enters the combustion chamber without passing through the carburettor is un-metered. This means the fuel to air ratio is unbalanced and in turn causes erratic engine performance. When air sneaks in like this, it causes the engine to run lean (lacks gas).
