A throttle cable on a lawn mower is a mechanical component that connects the throttle lever to the engine’s carburetor, regulating the engine’s speed. It’s crucial for controlling the lawnmower’s power and performance, allowing users to adjust the speed to match mowing conditions. Throttle cables are important because they ensure the engine operates efficiently and safely.
Why Do Throttle Cables Get Stuck
Throttle cables sometimes get stuck due to wear and tear, rust, debris buildup, or improper lubrication. When a throttle cable gets stuck, it can hinder the lawnmower’s performance, making it difficult to properly start or adjust the engine speed. Regular maintenance can prevent these issues. However, if you find yourself with a stuck throttle cable, we have a solution to fix your lawn mower in no time.
Fixing a Stuck Throttle 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 cable’s outer jacket 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. To get the cable out, you’ll probably have to remove a bolt and disassemble the lever assembly near the handle. Take a 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. 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.
