Replacing the ignition coil on a Ryobi handheld gas blower The Facts

If falling leaves and a broken blower are threatening to bury you beneath a pile of debt and debris, it's time to face the fix. Whether you are a seasonal garden enthusiast or a seasoned landscape professional, provides the parts, procedures and facts you need to fearlessly fix what fails you.

The ignition module is responsible for generating electricity, which it then transfers to the spark plug. Without electricity, there can be no spark, and hence; no internal combustion. While there are various reasons for ignition module failure, the primary symptoms usually manifest in the form of extreme difficulty starting your blower, and eventually, a no-start condition.

This article provides step-by-step instructions for removing and installing the ignition module on a Ryobi handheld trimmer. Let's get started.   The Facts REMOVING THE IGNITION MODULE [top]  1. Remove the blower tube.

FIX TRIX: You will discover that rotating the nut causes the fan and the motor shaft to rotate concurrently, precluding your ability to loosen the nut from the shaft. This obstacle can be overcome by removing the spark plug and binding the cylinder with a short length of starter rope.
