Link-Air

First i used pliers to get what was left of the key out and removed the blade driver assembly, then removed the belt guard to make it easier to work on. Then i ordered a new blade driver assembly and spacer driver from ereplacementparts.com, when the parts arrived i put a little dab of grease in the bottom of the blade driver assembly to help hold the spacer driver in place then slipped the assembly on the shaft, put the belt on the pulley and replaced the guard, put the mower blade back on, tightened the blade and then mowed the yard, everything fine so far.

Removed carb. and installed link-air and it was bottom oil seal leaking.I removed engine (4-bolts) and bottom pulley, removed old seal,installed new one.Bolted engine back on mower,replaced bottom pulley and belt.I changed the oil,and that was it. wasn't hard at all.

1. remove the shroud, three small bolts
2. remove the air cleaner
3. gently clean all the external parts of the tank and carburetor with solvent or kerosene and a brush
4a. image or note all the positions of the existing parts
4b. compare the existing position to the images in the parts diagram
5. take off the air vane from the magneto, one small bolt, take off the old link- air
6. take off the old link and spring remnants from the linkage, mark the holes with a sharpie
7. put the new link on, and test assemble the air vane, if it works freely, assemble with thread locker
8. put the new yellow spring on, the long end threads like a needle
9. put the smaller governed idle spring on, pay attention to which way the coil lays, it matters
10. put the shroud back on, the bolts don't need thread locker
11. carefully check start the engine, if it doesn't sound like your neighbors' it isn't right
12. if it does sound like your neighbors put on the air cleaner and happy mowing!
13. the new link-air is better than the old, so replace all three even if just one is broken or defective
