Have a pb-251 echo leaf blower that won't start what could the problem be?

The guy that said "Throw it away" is a moron. I have a Husq 225 blower, 12 years old, gets LOTS of use and still going. This idiot told everybody to buy 4 stroke equipment exclusively. 4 stroke blowers? No such thing. It's all about proper use and servicing.

The PB251 starting problem is probably a sheared flywheel key. If it's less than 5 years old, any Echo dealer will fix it free with the possible exception of freight. Any gas engine has to have 3 things to run: Spark (at the right time) compression and fuel/air. Take away any one of those and it won't start.

Listen to the experts...ME!
