What is the proper way to gap spark plugs?
Use your spark plug gap tool to adjust the gap. Gently bend the ground electrode in to narrow the gap or bend it out to widen it. Be very careful when making adjustments. Don’t bend the electrode more than a few fractions of an inch.
How do you gap a spark plug without a tool?
Using the gapper is simple. All you need to do is slide the spark plug electrode opening into the gap opener and gently move it over to the smallest side of the gapper. Once it hits the 0.02” area, press the electrode down until it’s flush on each end of the gapper.
What happens if your spark plugs are not gapped right?
Q: What Happens If You Don’t Gap Spark Plugs? A: Ungapped spark plugs will cause misfires as the gap between the electrodes could be too small or too wide. The air/fuel mixture then may not ignite or ignite on the wrong stroke, which can cause misfires.
Are NGK Spark Plugs pre gapped?
While most NGK spark plugs are pre-gapped, there are occasions when the gap requires adjustment. Care must be taken to avoid bending or breaking off the fine-wire electrodes. NGK recommends a round wire-style or pin gauge gap tool to measure the gap.
Does spark plug gap have to be exact?
The gap between the center and side electrodes of a spark plug must be an exact distance; otherwise, your plugs don’t fire efficiently. Adjusting the distance between the two electrodes is called gapping your spark plugs. You need a feeler gauge to gap your spark plugs properly.

How far off can a spark plug gap be?

What does a tune up consist of?
Generally, a tune-up consists of checking the engine for parts that need cleaning, fixing, or replacing. Common areas under inspection include filters, spark plugs, belts and hoses, car fluids, rotors, and distributor caps. Many of these only require a visual inspection or a simple test.
How do you work a spark plug gaped?
A spark plug has a relatively simple construction and is nearly maintenance-free, except for the adjustment (gap) of its electrode and periodic cleaning or replacement. Setting the gap on the spark plug electrode determines the voltage length and duration of the spark. A spark plug that has an improper gap will show certain signs and symptoms.
What if the spark plug is gapped to much?
Finest Total: OEMTOOLS Blade Grasp. Amazon. The OEM Instruments Blade Grasp has 26 calibrated blades that may measure sizes starting from 0.0015 to 0.025 inches.
How exact does spark plug gap need to be?
The gap on most mass-produced spark plugs ranges from 0.035 and 0.049 inches, with a tolerance of plus or minus 0.003 inches. Nearly all companies that mass-produce spark plugs pre-gap the spark plugs before they ship them out. Shipping and handling, however, may cause the plugs to move around, resulting in changes in the gap size.
What happens if the spark plug gap is wrong?
They include restricted air flow, lack of spark, and a deficiency or excess of fuel. The latter is usually caused by overuse of the choke. The smell of gas after repeated attempts to start your Weed Eater usually indicates that the engine is flooded.
