Customer Question
I have a ECHO PB251...
I have a ECHO PB251 Leaf Blower. Lines to the Carburetor was bad and so was the carburetor itself so I replaced all lines and filters plus the Carburetor. It will start but will not go up to RPM unless the chock is played with. I removed the muffler and ran it and still did the same

Have you tried to turn the high-speed screw on the new carburetor? Not unusual to have t adjust a new carburetor.

where is the high speed screw on this carburetor.
Technician: Curtis B., Technician replied 1 month ago

It should have two screws for adjustment, it may not! One would be the low speed and the other high speed. The left screw is high speed. It may take a special tool to turn the screws.

I should point out that when it starts I can not have the choke all the way open. it is about on 1/4 way down to keep it running and the RPM is good

I have tried the screws it takes a very little screw driver and no difference with the choke

I have tried the screws it takes a very little screw driver and no difference with the choke there is one on top and one on the side and I tried both
Technician: Curtis B., Technician replied 1 month ago

With you having to use the choke, the fuel mixture is too lean, and the choke is giving it more fuel and less air.

Technician: Curtis B., Technician replied 1 month ago

Could the fuel line to the carburetor be restricted?

[po
Technician: Curtis B., Technician replied 1 month ago

Hoses pull through the tank wall? Are the fuel lines letting a good supply of fuel through them?

Technician: Vince O., Small Engine Technician replied 1 month ago

Did you drain and clean tank and replace everything at once? Is the fuel filter on correct hose?

Carb adapter tight, no cracks and gaskets good?

Ask Your Own Small Engine Question
Customer reply replied 1 month ago
new gaskets
Technician: Vince O., Small Engine Technician replied 1 month ago

D​id you replace fuel lines, filter and carb all at same time? sounds like a fuel/carb problem or an air leak. Does it spit or sputter or run erratic?
