Know before you buy
This kit is specifically designed for Briggs & Stratton Quantum series engines, including the 625E, 675Ex, 725Ex, and standard 625-675 series. It is intended for 4-cycle push mower engines ranging from 3.5 to 6.75 HP.
The kit provides the essentials for a seasonal tune-up: 18 ounces of 4-cycle 30W engine oil, a bottle of fuel treatment and stabilizer, a replacement air filter, and a boxed spark plug.
The stabilizer helps prevent fuel degradation during periods of inactivity, such as winter storage. Using it ensures your mower starts reliably when the next mowing season begins.
No, this kit is strictly for 4-cycle engines. The included 30W oil is not formulated for the fuel-oil mix required by 2-cycle equipment.
It is standard practice to perform a full tune-up using these components once per year, typically at the start of the mowing season or after every 50 hours of operation.
