Why is my spark plug so hot?
Causes of Overheating: Spark plug heat range too hot. Insufficient tightening torque and/or no gasket. Over-advanced ignition timing. Fuel octane rating too low (knock is present)
How do you know if your spark plug is hotter?
The higher the number, the hotter the plug. The lower the number, the colder the plug. Starting with part # 24 (heat range 4), if you want a colder plug you would use part # 23 (heat range 3), for a hotter plug you would use part # 25 (heat range 5).
Will a hotter spark plug burn more fuel?
A hot spark plug maintains a higher internal operating temperature to burn off oil and carbon deposits, and has no relationship to spark quality or intensity. Conversely, a “Cold” spark plug has a shorter insulator nose and absorbs more combustion chamber heat.
When should I run a hotter spark plug?
If it the heat range is too hot, your engine could experience detonation, pre-ignition, or power loss. Most spark plug manufacturers recommend that the tip temperature remain between 500° C and 850° C.
When should you run a hotter spark plug?
If some of the plugs are clean and others have dry sooty lamp black deposits, the sooty plugs are getting too much gasoline, and can be corrected with carburetor adjustments. If a leaner mix is used, and the engine runs irregularly or misfires, go back to original setting and consider a hotter plug.
How do you tell if a spark plug is fouled?
A fouled or bad spark plug is a plug that has become covered with a substance like oil, fuel or carbon or one that is blistered from running too hot….Symptoms of bad spark plugs can include:
- Reduced gas mileage.
- Lack of acceleration.
- Hard starts.
- Engine misfires.
- Rough idling.

What kind of wire is a spark plug?
Today, let’s dive into spark plug wires and the developments in technology that these simple conductors have experienced over the years. That’s what a spark plug wire is—a conductor. At its basic level, the spark plug wire exists solely to transmit electricity from the coil or distributor to the spark plug.
What should the gap be on a spark plug?
The gap is .032 if under 20psi. If boost is 20psi or more, close the gap to .028 ***When adjusting the gap on your spark plugs, never pry, apply or exert any force on the spark plug center electrode, or center electrode ceramic insulator.
Why do I need a lower resistance spark plug wire?
The higher voltage of a coil on plug or distributor system can create enough voltage that a slightly higher resistance wire will not greatly affect spark strength, but the relatively lower output of a magneto means using a lower resistance wire is more important to ensure a hot spark from the spark plug.
