Most often on this model, the 'spark arrestor' screen is plugged. it is located on the end of the removable exhaust pipe. Clean with a wire brush.

Tammy,buy your spark plug from Autozone,Stihl has a high mark up.2.40 from A.Z.

According to my Stihl technical reference this is not a blower, vac, shredder. Model number wrong. HS prefix is for a hedger.

Disconnect the spark plug wire from the spark plug and ensure it can't come in contact with the spark plug. Removal of the spark plug wire removes any possibility that power can be supplied to the engine of the blower during the repair.

Remove the screws that hold the air filter cover in place. Remove the air filter cover and air filter. Remove the air filter housing from the side of the machine. Removal of these components allows you access to the primer bulb, fuel line and carburetor.

Can be Tank airiation, sparkplug, leaking crankshaft seals, (L+H adjustment without knowledge) or clogged carburetor , sludged filters in tank carburetor or fuel tap problem , clean first allways the airfilter before all.
bad
If noting worked then look the color of spark it must be whiteblue
LAST remove the exhaust muffler and look your piston that it is smooth if its smooth there can be a broken piston-spring.

fuel starvation
check the inline and fuel tank filters
and also the tank lid has a small gas presure release on it
this may be blocked causing a vaccume
try to also replace the paper air filter and also the spark plug
clean the fuel out and replace it start it and drain the carborator
with more fuel to run it out
if this fails to help
you may need to clean the carb

i dont think its anything serious
although it could turn out too be a faulty ingition pickup coil
{feeds the spark plug with juce}

Check the spark arrestor, or the exhaust port are not blocked with carbon.

The air gap for the ignition coil core to flywheel is adjustable on some engines and the gap does vary.
On a Stihl, I used a matchbook cover first, then doubled it and got the engine to start. That amounts to 8-10/1000ths (0.008-0.010") as measured with a digital caliper after-the-fact.
I'm troubleshooting another engine currently from a McCulloch Airstream IV that only has ~12 hours and no spark but the coil measures roughly as it should; around 1K Ohms. Was surprised to find the company went bankrupt in '99. Another one killed by Asians and fairly poor design.
