I easily returned my purchase.
To my surprise my boyfriend had already done the maintenance on the blower this part was purchased for. That being said I returned it. So, my review is more about the easy return process. The customer service agent I spoke with was super helpful with the return, a label was sent to my email and the product was returned.

Probably a Great Spark Plug
The spark plug probably works great. Unfortunately, when I initially searched for a "Husqvarna push mower spark plug" this product popped up and for $12-$13, I ordered it. This plug is for a weed whacker, back pack blower, chainsaw, etc... It didn't say anywhere that this plug WASN'T for a mower, so I assumed it would work. But it's too small. This isn't eReplacemntParts fault, it was mine. Granted it would've been nice if it clearly stated this plug wouldn't fit a small push mower. Now I've learned that there are two different size spark plugs on the market and also that I should always ask questions if I'm not sure. I would've given 5 stars if the ad clearly stated "Not for Lawn Mowers". I'm sure i'll continue to buy products from this site because shipping was fast and the price was pretty decent.

1. Using a 5/8 spark plug socket wrench, I unscrewed the old spark plug and replaced it with the new spark plug, tightening it 1/8 turn after it touched the engine.
2. Unscrewed the thumb screw on the air filter cover, removed the foam filter. With a rag, I cleaned the edges of the air filter inlet where dust had settled. I soaked the new foam filter with 2 cycle oil, squeezing to get excess oil out, then installed the new foam filter and replaced the air filter cover and tightened the thumb screw.
3. Done

Put in new parts but it did not fix the problem. After taking carb apart, I cleaned everything in sight including all screens etc.. put it back together and original problem continued ! I then thought some of the little channels in the carbs body may be clogged. Not having an air hose , I took the carb apart, I put the carb body in my wifes jewelry cleaner for a couple of cycles. Eureka !! I now have blower that works like new. By the way, my new gas filter and spark plug work great.
