It is the same as an ignition coil on all internal combustion engines. It is a high voltage transformer that provides a spark at just the right time to ignite the air-fuel mixture in the combustion chamber.
The gap should be between .006 and .010 if it has aluminum clylinders. The gap should be between .010 and .014 if it has cast iron cylinders.
Then ignition of the fuel/air mixture in the cylinders will cease, and you won't be going anywhere.
0.010-0.014"
take the air filter housing off on left side the ignition coils
.010 to .012"
The easiest way is to use a standard business card between the coil and the magnet part of the flywheel.
Ignition misfires and "sputtering" can be caused by any number of system failures such as air/fuel, ignition and even emissions/exhaust. A failing ignition coil, control module, plug wire and plug are often components that should be examined when diagnosing such misfires.
Ignition coils generate the voltage needed to create the spark for ignition of the fuel air mixture, without it the vehicle will not run.
No, there is no coil or Spark Plugs. Ignition takes place due to heating from compression of the fuel/air mixture. Some diesel engines have a "Glow Plug" for aid to starting in very cold weather.
The gap should be about .0125 in. (.3175 mm.) or the thickness of heavy paper.
When looking at the engine, the coil will be on the passenger side of the engine. Look at the air intake tube box, follow it up to the throttle body. Next to the throttle body on will be the coil. Its a single coil, not coil over plug design. Erik
