The ignition coil in a two-cycle motor, like people in a Poulan leaf blower, is a mini transformer. It transforms a low-voltage battery’s power to the high-voltage needed for combustion to occur. Electrical errors, like a continually worn out spark plug, are a indication that the ignition coil may have problems. Replacing the coil on a Poulan blower involves dissembling down the machine to just the motor.
Unplug the spark plug and cable. Unscrew the air filter cover and then eliminate it as well as the filter. Unhook the throttle linkage in the carburetor. Unscrew the most important engine cover and eliminate it. Remove the spark plug using a wrench.
On the side of the blower, unscrew and remove the fan casing. Pull out the fan blades and washer beneath them. Unscrew the fuel tank and slide it out of place. Unscrew the motor mounting screws on this side of this machine. This may require an Allen wrench based on the version. Pull the motor from the remainder of the meeting.
Unscrew the ignition coil and then eliminate it as well as the washers and spacers. Transfer parts to this new coil starting with the on/off switch. Attach the cable retaining grommet in addition to the spacers and washers in the old coil.
Attach the new ignition coil into the motor and screw it in just until tight. Expand the fly wheel till the magnets are no longer facing the coil. Place a sheet of card stock between the coil and the fly wheel. Loosen the screws holding the coil in place, then re-tighten them to ensure appropriate spacing between the coil and the fly wheel. Expand the fly wheel so the magnets are aligned.
Reassemble the machine, starting with putting the motor back into place and pulling the on/off switch wires to the handle. Replace the motor mounting screws and fuel tank using its mounting screws. Set the drier and fan blades back on to this machine, and screw the casing over them. Attach the main cover and then hook the throttle linkage back in the carburetor. Plug in the spark plug in addition to its cable and bend. Replace the air filter and screw its cover above the surface.
