How does a throttle cable work on a push mower?

Your lawn mower’s throttle cable controls the machine’s engine. It’s the part that kick-starts the engine and commands the speed of your mower’s blades. If the engine dies down or the mower doesn’t respond to adjustments in the throttle handle, you may want to troubleshoot the throttle cable.

How does the throttle on a lawn mower work?

When the crankshaft spins quickly, the flyweights open up, putting pressure on the governor cup and crank. This closes the throttle, limiting the air-fuel released into the engine. When the engine load increases, the crankshaft spins more slowly. This leads the flyweights to relax and the throttle to open back up.

Can a throttle cable stretch?

Sometimes a cable can become stretched over time, which will not only delay the response of the throttle, but can also leave the cable more susceptible to breaking. Delayed response may also be indicative of the need to have the cable slack adjusted.
