Take pictures of fuel line, primer line and return line routing.
Remove carb for access to tubing routing.
Remove all fuel lines and replace with new parts. You may need to trim off the tip of the tubing at an angle in order to get it through the appropriate holes. You may also need to slip a small wire t ... Read more hrough the tubing so you can control it as you fish the tubing through the required holes.
Hook up tubing and reinstall the carb.
Oil the foam air filter and wring it out thuroughly. I like to wring it with a paper towel or rag. Install.
Add fresh, non ethanol gas if you can get it.
Start the saw and get it a little warmed up. Probably a good time to adjust the carb. Check YouTube for instructions.

Replacing the air cleaner filter and spark plug were simple and quick. There were 4 torx head screws to remove the cover. The screws also have a slot for a straight-blade screwdriver, but it was worth it to get the Torx set.
Replacing the auto feed line assembly was straightforward, except there is a somewhat hidden setscrew on the inside of the shaft that must be removed. No replacement instructions came with the assembly, so I struggled with removing the old one before finding the setscrew. Once I removed it, the assembly removal and replacement was quick and easy.
The trimmer starts, runs, and doesn\'t leak.
Would not run
