What does oil on a 2 stroke spark plug mean?
Oil only collects on spark plugs in two-stroke engines, like those in chain saws and leaf blowers. That’s due to how oil lubricates different types of engines. You may find oil on a spark plug because: Too much oil was mixed with the gasoline. The piston rings (the component that seals piston and cylinder) are failing.
What happens when a spark plug is soaked in oil?
When a spark plug is soaked with oil, it will have difficulty making a spark and will not be able to maintain the right temperature in the cylinder, thus ignition might occur too late or too early, if at all, thus resulting in engine misfire. An engine backfire occurs when the fuel is ignited at the wrong time.
Why does my 2 stroke engine not run?
The reason the machine will sit idling with no problem is because it is getting enough fuel for the level of engine speed required, however as soon as we try to increase that speed where we need more fuel there won’t be enough available. Here are 10 reasons and fixes to help prevent lack of fuel to a 2-stroke engine. 1. Mixture Screws
How to check the spark on a 2 stroke engine?
To check spark, we are going to pull the spark plug, if the spark plug is wet, there is a good indication we ARE getting fuel. If the plug is dry and we have spark, we are not getting fuel. So to check the spark we need to pull the rubber cap off the spark plug and remove the plug from the engine.
What causes a two stroke engine to surging?
The most common causes of a two-stroke engine surging include lack of airflow, contaminated fuel, faulty or old spark plugs, or a maladjusted carburetor. Fixing each of these issues involves removing parts of the engine, inspecting, and possibly replacing the equipment.

Why does my spark plug not make a spark?
An engine backfire occurs when the fuel is ignited at the wrong time. When there is oil on spark plug threads, the engine will backfire. An oily spark plug might not be able to make a spark at the precise moment when the exhaust valve opens.
