Echo blower. PB210E

[Knots]

Blower starts and runs fine for a couple minutes and then starts to slowly reduce speed with throttle wide open until it quits. Pulling choke will let it run a few seconds longer. Will start again in a few minutes with same end result.
Any thoughts about where to start would be greatly appreciated.
Thank you,
Knots

Are you using Echo 2 cycle oil & 93 octane fresh gasoline? If not give it a try.

Page 3 in above manual states 89 octane minimum.

Thank you Mechanic Mark. Especially for the manual.
Figured it out I believe. Plugged fuel filter.
I was fairly sure it was a gas cap vent issue but I ran it with cap on tight at WOT and no problems with new filter installed.
Thanks again.
