What is the gap on a spark plug for a 50cc scooter?
I’m 100% sure this depends on the exact scooter model (and possibly which spark plug is used), as different engines will have different ignition system and different types of spark plugs, etc. If you have absolutely no clue, you can probably try a 0.6mm gap (or 0.025″ if you prefer non-metric units).
Can a spark plug be used in a small engine?
If you have an old automotive spark plug laying around, don’t try to use that in your small engine. They are too long and even though they might not hit the piston, they will be in the wrong position to ignite the fuel. I know…..I tried them.
How are spark plugs used in port injection engines?
Port-injection engines inject fuel during the intake stroke, while direct-injection engines, gasoline or diesel, might wait until the compression stroke. Finally, heat is provided in one of two ways: one or two spark plugs for gasoline engines, or the heat of compression for diesel engines.
What happens when you have a spark plug problem?
Fuel Economy – If you’re tracking fuel economy, as everyone should, spark plug problems might cause your engine to consume more fuel than usual. As the ECM has no control over spark strength or oxygen content, it adds fuel to compensate for poor combustion. Misfire – A cylinder misfire occurs when the spark plug can’t ignite the air-fuel mixture.
What’s the best way to replace a spark plug?
Replace scuffed, worn, or damaged spark plugs wires or boots. Blow Out Spark Plug Channels – Debris tends to collect in unprotected spark plug tubes and channels. Compressed air is a good idea to get rid of it, preventing it from falling into the cylinder when you remove the spark plug.
What should I do if my spark plug is not working?
Lubricate New Spark Plug – Using just a dab of anti-seize lubricant, silver or copper doesn’t matter, lubricate the spark plug threads and gasket. Install New Spark Plug – Spin the spark plug in by hand until finger tight, then torque to specification.

Where do you change the spark plugs in a car?
For most vehicles, replacing spark plugs is a simple matter, though you might need to be a contortionist to get to some of them, perhaps placed behind shields or under intake manifolds and other equipment. Here are the basic steps to replace spark plugs.
Where does the charge from a spark plug come from?
High voltage, 5 kV to 45 kV, depending on the vehicle, is generated in an ignition coil, controlled by a distributor or engine control module (ECM). The charge is conducted to the spark plug via a spark plug wire. The spark occurs when the charge jumps between the spark plug electrodes, just 0.01” to 0.07” (0.25 mm to 1.8 mm) across.
