Two NGK Spark Plugs – BCPR5ES, Replaces Champion RC12YC.
A: This spark plug should have a gap set to 0.02 inches.
With varying spark plug gaps and lengths, it`s important to buy the right ones when it`s time to replace yours. Spark plugs that are too long can protrude into the cylinder and cause piston damage. Meanwhile, spark plugs that are too short will struggle to ignite and often cause engine misfiring.
The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.
Found in many passenger vehicles, hot spark plugs have more insulation to transfer the heat slowly, which keeps the temperature high enough to burn off carbon deposits and avoid premature fouling. This helps allow for more time between spark plug changes.
Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
For most racing applications, you usually want the plug gap to be between 0.020 and 0.040 of an inch. Most engine builders seem to settle around 0.035 of an inch. Factors such as the type of ignition you run, cylinder heads, fuel and even timing can affect how much gap will work best for you.
The gap setting is different for each vehicle but most are somewhere between 0.028″ and . 060″. Consult the owner`s manual or Champion ® catalog to find the recommended setting for the vehicle you`re working on.

WHAT IS THE SPARK PLUG GAP 173 O/V CUB CADET\
I have a cub cadet 2165 I just put in a new battery and it is slow turning over any ideas?
If battery is good and everything is hooked up right. Most likely could be the pto clutch bearing. Not the bearing on the pulley but on the clutch inside. Had the same problem, took the spark plugs out got it free. Turned over easy with plugs out, Started right up after and then burned up my bearing. Don’t burn up bearing. If do field assy. For that is 200$ if you can get away with just that. Otherwise 350-400$ for full assy.
