Possible need tune up carb clean or repair and or exhaust port clog
If the carburetor is not fouled and adjusted properly then likely there's a crankcase leak.
Try increasing idle fuel mix in eight turn increments and see if it improves.
To diagnose leak search "2 cycle crankcase leak"

I don't mean to over simplify this, but are you using fresh gas? Gas blowers are extremely ticky when it comes to gas. They like it SUPER fresh. And while the gas and oil mixture should be right, it can be off a little bit and still run. Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with gas blowers, and it fixes the problem 75% of the time. Also make sure your spark plug is clean. If you are not sure, a new plug couldn't hurt.
Hope this helps!!

check and see if the muffler is plugged and it can't get rid if it's exhaust.

Have you tried cleaning the carb?
Testimonial: "Thanks for the suggestion, that sounds like what it may be. "

Likely dirt in high speed needle valve(H); could be leaky fuel line(air leaking in), plugged fuel filter, pinched fuel line, etc - anything restricting flow of fuel. Likely, you aggravated an existing problem by cleaning the air filter which would have been providing some choke effect if it were partially plugged.

Hi
This is either a clogged muffler or carb. Take the off and see if it will rev. If not you need to clean carb and install a carb repair kit. Do not run long with muffler off.
