What is a throttle cable on a lawn 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 do you fix a seized throttle cable?
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).
Can you use wd40 on throttle cables?
Choosing The Correct Lubricant Some cables have a slick inner sheath that will gum up if exposed to solvents or harsh chemicals, so do NOT use WD-40 or any other type of penetrating oil. Regular motor oil works great if you don’t have an appropriate aerosol product.
Why is my throttle cable not snapping back?
If the throttle does not completely return the cable may be binding, incorrectly routed, frayed, or corroded, which warrants further investigation. With the bike OFF, twist the trottle open to the stop and let go. Make sure the throttle returns to the closed position quickly and easily.
Why is my throttle cable stuck?
The throttle and the throttle cable are the usual culprits to a sticking throttle cable. But if you have tried cleaning and/or replacing the throttle and cleaned the cable and it’s still sticking, you can also check where the cable connects to your carburetor.
Why does my lawn mower not throttle?
If your lawnmower will start up and idle, but then dies when you throttle it up, you might have a problem with the carburetor. The carburetor brings air and fuel together and mixes them in a perfect ratio for combustion. Fuel makes its way through the carburetor using several different passages.
What size is throttle cable?
Inner Wire Diameter: The diameter of the inner wire, 1.2mm & 1.5mm commonly used for throttle and choke cables, and 2.0mm, 2.5mm, 3.0mm used on clutch and brake cables.
How do you measure cables?
Measure electrical cable diameter with a wire gauging device. To do this, clamp the two halves of the diameter gauge around the cable at various circular fittings until finding the one that encircles the wire snugly without biting into the outer jacket. Read the diameter figure by that circle.
