If your ECHO chainsaw can not start after several months of storage, that means your carburetor may need a new rebuild kit or a complete carb replacement.

How To

Step 1: You can begin by removing the filter cover and the air filter. Then you should try to start it with some starter fluid to make sure it still runs.
Step 2: Remove the three screws on the top engine cover to take it off. Now unscrew the screw on the top part of the handle and remove it, then lift up the rear panel and remove the fuel lines going to the primer bulb.
Step 3: Then remove a rubber grommet on the kill switch wire, and maneuver the panel to release the throttle linkage from the carburetor. Now remove the rear panel and unscrew the three screws holding the intake adapter to the carb.
Step 4: Next, you can lift up on the choke lever and maneuver it off the carb. Then you need to gently pull off the impulse line to the top part of the carb and unscrew the Phillips screw on the top. Now remove the top plate on the carb and examine the pumping diaphragm. If the diaphragm is quite stiff, you need to replace it with a new one.
Step 5: Reinstall the pumping diaphragm followed by the paper gasket and then the top plate. Replace the Phillips crew on the plate and then move to the other side by replacing the diaphragm gasket and the metering diaphragm. Now you need to reinstall the bottom plate along with its four screws.
Step 6: Reconnect the impulse line and replace the three screws for the carburetor and the intake adapter. Next, reconnect the throttle linkage to the carburetor and then replace the rear cover plate. At this point, you want to make sure the throttle linkage is inside its guide prongs and then check its motion before you reconnect the fuel lines to the primer bulb. Now replace the rubber grommet on the kill switch wires and then put the top part of the handle back on. And finally replace the air filter, the top cover and then the filter cover.
