My leaf blower was working fine and then all of a sudden it stopped working

Sounds like it's seized. Did the gas have the right oil mixture?

If it's only a few months old it will still be covered by the manufacturers guarantee.

Check wiring, switch, then motor, for any damage.

set you HI --LOW adjustments-- mine crasftsman-blower needed this after the first season. factory set is to low--- in order to pass EPA.

It sounds like it is time for a new ignition module. Get the model, type and code off the blower housing and go to www.precisionope.com. There you can look up the ignition module under OEM parts.

The blower was still under warranty and Toro is replacing it.

How did you do the spark test? Did you use an in-line spark tester? You need to determine definitively that there is no spark and the only way to do it is to use an in-line spark tester...you can get one at Harbor Freight for about $12. After you've checked it that way, if there is definitely no spark, most likely the ignition module is faulty. You should be able to purchase a new module through Sears Parts but bounce the cost and time of that off of the cost of a new blower...you may be surprised.

first check for spark, if you have spark gap plug at .030. turn mixture screws completelin give a short squirt of carb cleaner directly into throat of carb and try to start if unit starts then dies ,carb needs to be rebuilt and also change fuel filter in the gastank. gas mixture 40:1

Diaphram gasket in carb is swelled and air is getting through,get a carb reduild kit and it should be fine.

IN the tank there is a intake tube on the bottem of that tube is a tiny filter. you can reach in and pull it out the tank enough to work on it.
It is clogged pull it off let it dry for a day and then blow it clean fron the gas line side OUT.
