Im not real happy with my echo leaf blower right now. I bought one two years ago with a five year warranty that recently stopped working. Turns out there are a lot of exceptions to the warranty. For example, the unit is approved for use with ethanol gas, but somehow if it screws up the carb its not covered under warranty.
My old el cheapo poulan lasted ten years at about half the price.
Don't take this wrong.....but,
A warranty does not cover stupidity.
Ethanol and carbs are not compatible.
Use non-ethanol gas (if you can) and your troubles should be few.
Most people buy a gallon or five of that wonderful ethanol your government is shoving down your throat, mix it 50:1 (maybe) and it sits in the garage for the summer or even better, all winter.
Then in spring they pull their 2 stroke whatever brand, out of the garage,
fill it with the gas they have in their can and expect to trim away like when she was new.
99% of the people with trouble didn't winterize or care for their fuel or carb in anyway.
According to your machine's Manuel, you should throw out any ethanol gas that has sat for 30 days or more.
