You leaf it alone!

Electric leaf blowers are preferred by many over gas blowers. One primary benefit of an electric blower is that you do not have to buy gas.

what is the gas mixture for an echo leaf blower P B260 L
The average cost of operating a gas leaf blower would depend on its usage. The cost would depend on the blower itself and it can be reduced if one is using an effective and high quality one, for example Stihl, Toro or Black & Decker.
50:1 regardless what the prior manuals say, thats what my manual from echo says as of 1/4/2013
If you have not started the blower, simply dump the fuel out. If you have started the blower and it ran for just a short time i am afraid you have done serious engine damage to the blower. The cost to repair it would far exceed value of the unit.
