The Autolite 2956 spark plug for the Green Machine 3000HB blower and other equipment delivers the spark that lights the fuel in the engine's cylinder.
- One of the Autolite copper spark plugs, engineered for quick starts and the power your equipment needs.
- The copper core center electrode aids thermal control and improves resistance to fouling.
- Nickel center and ground electrode tips are specially engineered for extended life.
- The high alumina multi-rib ceramic insulator gives thermal conductivity and insulation for increased strength.
- A nickel-plated shell resists corrosion for added durability.
A worn or fouled spark plug can show up as hard starting or rough running, and its firing end can look sooty or oily. Those signs alone don't prove the plug is at fault, since stale fuel is another common cause.
The Green Machine 3000HB blower, the HMC 3000HB blower and the McCulloch Eager Beaver Backpack Blower each take one plug, and this spark plug also fits a wide range of Homelite, McCulloch, Craftsman and Ryobi equipment. If your machine isn't named here, open the "Vehicles it fits" section to check your exact model and engine.
