Lawnmower throttle cables can get stuck because of rust and grit, making it difficult to control the mower. Here's how to access and lubricate it so it moves freely.
By the DIY experts of The Family Handyman Magazine:April 2012
Stick the end of the cable into a funnel and wrap electrical tape around it
to create a seal. Spray or pour penetrating oil into the funnel. Position the
opposite end of the cable over a small container to catch the penetrating oil as
it drips out. Then lubricate the cable.
Remove the air cleaner assembly so you can see the choke plate. With the
throttle control lever in the “choke” position, pull on the outer jacket of the cable
near the clamp until the choke plate opens. Tighten the clamp with the cable in
this position. Reassemble the air cleaner.
If your lawn mower's throttle cable is hard to move or stuck, here's a fix. Disconnect
both ends of the cable from the mower. You'll probably have to remove a bolt and
disassemble the lever assembly near the handle to get the cable out. Take a digital
photo to help you put it back together when you're done.
At the engine end, loosen the clamp that holds the cable to the engine and
unhook the cable from the carburetor. Pour penetrating oil into the cable (Photo 1).
Grab the inner cable with pliers and work it up and down to loosen it. When the
cable moves freely and all the penetrating oil has drained out, squirt silicone lubricant
into the funnel to keep the cable sliding freely. Reinstall the cable (Photo 2).
Have the necessary tools for this DIY project lined up before you start—you’ll save time and frustration.
