Spark plug and air filter were easy to change. Fuel filter needed a piece of hanger wire to fish it out of gas tank and changing it was easy. Now my blower starts with one pull.

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 wif es 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.
