Will a hotter spark plug stop fouling?
Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean might contribute to preignition or detonation.
What does white tip spark plugs mean?
Blisters on the insulator tip, melted electrodes, or white deposits are signs of a burned spark plug that is running too hot. Causes can include the engine overheating, incorrect spark plug heat range, a loose spark plug, incorrect ignition timing or too lean of an air/fuel mixture. The spark plug should be replaced.
What happens if you tighten spark plugs too much?
Simply put, over-tightening your spark plug can cause damage to the wire. Specifically, it can damage your spark plug thread, which means you’ll have to replace the spark plug wire repeatedly. To avoid this, learn the torque recommendations for your vehicle, as suggested by the manufacturer.
What happens if spark plugs are too loose?
What Will Happen if Spark Plugs are Too Loose? Too loose spark plugs typically leads to poor performance and eventually engine damage!

Why is my snowmobile not getting spark?
Disconnect the main electrical connector coming out of the engine, and then check for spark again. This unhooks the kill switch, ignition switch and wiring for those switches. If the spark improves, the problem is within wiring from one of those switches or a switch itself is to blame.
Does indexing spark plugs help?
Indexing spark plugs can prevent pop-up piston dome contact from closing up the plug gaps and May also enhance flame propagation in older inefficient combustion chambers. Spark plug indexing sometimes is necessary to avoid side-electrode contact with high-dome pistons.

Should I run a hotter or colder plug?
Air/Fuel Mixture: Lean air/fuel ratios raise cylinder-head temperatures, requiring a colder plug. Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean might contribute to preignition or detonation.
What happens if you run too hot of a spark plug?
If the tip of the spark plug is too hot it can cause pre-ignition leading to detonation/knocking and damage may occur. If it is too cold, electrically conductive deposits may form on the insulator causing a loss of spark energy or the actual shorting-out of the spark current.
What happens if spark plug is too hot?
How do I know if my spark plugs are tight enough?
Below, we discuss the symptoms associated with over and under-tightened spark plugs. You’ll learn how to find out if yours are tightened correctly, and the proper installation procedure to get it right.
