Echo PB 265L - Throttle Issues

should be two air adjustment screws, at full throttle or as close as you can get to full throttle, open or turn screw counter clockwise take note on how much you turn it, in the event it does not help, try one then the other as on of these will help 96% sure. have a great day

Hi ryan...
You still have problems in the carb highspeed circuit..some debris in the passages...
BE SURE TO USE COMPRESSED AIR TO BLOW OUT THE CARB.
(be sure to watch the inlet valve seat, you can loose it and not even know it) Blow the carb clean in a box or something that will contain any part that may be expelled during cleaning.

Hi dbooth
Make sure your fuel lines are connected correctly.

Remove the in tank fuel filter and take it apart, the felt Echo uses on the filter clogs quickly. There is still a mesh screen filter in the assembly so make sure you put it all back together and reinstall the fuel filter into the tank.

Most likely there's a problem with fuel supply - choking cuts air supply optimizing the air/fuel mix. Most common solution is to check and clean the carburetor.

If there's a tiny fuel filter in the fuel line between tank and carburetor check it on excessive pollution. Replace it when necessary.

When opening the blower for carburetor cleaning - also check the airfilter and replace when dirty.

If never opened the blower - take pictures with a digital camera at each step. The pictures can help with assembly after cleaning.

The choke system is connected to the half throttle position, if you lift the throttle trigger the choke pull will automatically return, whilst trying to start do not lift the throttle trigger, the starting procedure is, pump the primer bulb as many times as it takes to 3/4 fill the bulb, pull the choke pull fully out, this will switch the saw on and engage the half throttle, crank the engine until it fires once, do not continue to pull,it will actually not run on full choke, if you do continue to crank with the choke fully out, you will very quickly flood the engine, now push the choke fully in, now crank the engine until it fires up, lift the throttle trigger once, this will dissengage the half throttle, and it should now come down to idle.

The choke actually just opens the throttle bodies a little (the bike is fuel injected). Try using putting on the 'choke', then pressing the start button, but dont touch the throttle. Does it start ok? Also, when started, if you use the 'choke' does it increase the engine speed? If it does not, then you need to set it up correctly.
Let us know how you get on.

Check the muffler and/or spark arrestor screen in the muffler outlet pipe and also the engine's exhaust port behind the muffler. These are prone to carbon-clogging and the engine cannot "BREATHE" enough to reach full throttle. If all-clear in the muffler, go back in the carb and locate the inlet screen directly opposite of the inlet needle. Carefully pull it out with a pick and hold it up to a light source. If you cannot see thru it, replace it. This is another, (less) common area of obstruction.

Hope this helps,
Dolf-

Turn on ignition switch, Choke, prime bulb 5 times (or until fuel flows), hold throttle down and pull starter cord sharply until it tries to start, then place choke in mid position pull cord sharply again until it runs then move choke to off when it will allow it.
Also you can go to toro.com then customer care, then manuals and parts then type in model no. and download an owners manual.
