Question about Echo Leaf Blowers
I own a Great piece of Landscape equipment. It's a Echo PB 400e Backpack Blower. The best piece of Landscape equipment I own. This is the first problem I've ever had with it, that I could not figure out.
What I need your advice on, is: "How to adjust the carburator"? It will run, but not at high RPM. I have "tried" to adjust the carburaotor myself, but it simply is not operating at what it is capable of Last week I "thought" that I had it (fairly) well adjusted, but no! It ran (ok) for a few minutes then it simply would not, nor will it, operate at full throttle. Nor has it done so since last week. I have (Incorrectly) turned the 2 adjustment screws, on the carburator, in vain attemepts to get it to operate properly. Additionally I have (Incorrectly) adjusted the one larger adjustment screw, on the carburator, that is right next to and under the "choke" lever. If this screw is screwed to far out the choke lever will not operate properly. It interferes with the choke lever. Preventing the choke from being fully applied.
Perhaps there is a basic series of revolutions 1 way or the other, that these adjustment screws are supposed to be set at? Also do you have a service manual for this unit availble for sale? If so, can I order it through you? Where, if it's available, can I obtain a service manual for my Echo PB400e Backpack Blower?
If possible, your advise and assistance will be greatly appreciated.
Hi. Does anyone know what year my Echo pb 400E Backpack blower is?

I don't mean to over simplify this, but are you using fresh gas? Gas blowers are extremely ticky when it comes to gas. They like it SUPER fresh. Not fresh from the gas can, fresh from the pump. And while the gas and oil mixture should be right, it can be off a little bit and still run....but fresh gas is essential! Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with gas blowers, and it fixes the problem 75% of the time. Also make sure your spark plug is clean. If you are not sure, a new plug couldn't hurt.
Hope this helps!!

The problem with my pb400e is simular, however the main problem
my unit has is fuel pouring out of the caberator. I bought a new carb, but when I installed it the same thing happened, fuel pouring out of the carb. I took out the carb looked into the cylinder and noticed the piston does not look like it comes down far enough to burn all the fuel, and maby thats where the fuel is comming from. does this sound like maby the end of the life of this motor.
