No power with Echo PB-755st Leaf blower

Try pulling the air filter off and see if it picks up. Also a minor carb adjustment may help. Also make sure your fuel isnt old or watered up. See if you can find alcohol free gas in your area. It may cost a bit more but it saves on repairs!

What is the oil mix for 2 gallons of gas for a 2 cycle gas leaf blower

Only use 50 to 1 as that is what is specified.

To get 50 to one ratio with the 6.4 oz bottle of 2 stroke oil just add 2 1/2 U.S.. gallons and that will be 50 to 1 ratio so you will have the correct ratio .

Need to find the oil to petrol ratio for Husqvarna 132 HBV blower


50 parts fuel to 1 part oil. The easiest way is to purchase the little premix bottles of Husqvarna oil- one bottle to one gallon of fuel. You can find premix oil bottles at the dealer that sold the blower.

Started with straight gas- can it be flushed and restarted with gas /oil mix?

Yes you can dump out the straight gas and mix some two cycle fuel mix I would mix it a little rich like 32 to 1 thats eight ounces to two gallons of gas but if you ran it with straight gas for a long time it wont help

  • Echo recommends 89 octane fuel and 50:1 mix to one gallon gas for your pb2100
  • go to this site and find fuel and read about it if you would like
  • i use 40:1 in everything i have and have had no problems
  • The oil you buy make sure it is for 2 cycle engines and not outboard motors
  • 50:1 =2.6oz to i gallon gas
  • 40:1 =3.2 oz to i gallon gas

Proper gasoline and oil mix ratio.

My echo uses 50-1 ration. Home Depot sells the small containers for Echo Leaf Blowers that you mix with one gallon of gas.
