Description
Overview:
The Decomp Lever Cp - Robin Part - RB228 35531 11 is a metal engine component for Robin/Subaru small petrol engines used on construction and garden machinery such as generators, plate compactors, pumps, and mowers. Fitted to the valve gear, it momentarily opens a valve to reduce cylinder pressure during starting. This makes pull-starting easier, lessens kickback, and reduces stress on the recoil starter. Built from durable metal for long service life, the lever offers stable, repeatable operation in demanding site and outdoor conditions. It is a practical like-for-like replacement for a worn or bent lever, restoring correct decompression function and improving start-up consistency. Reference: RB228 35531 11.
Key Features:
- Durable metal construction for long service life in workshop and outdoor use
- Lowers cylinder pressure to reduce pull force and aid cold starts
- Helps minimise kickback and strain on recoil starters and pawls
- OE-style geometry for consistent valve actuation and reliable timing
- Compact lever design suited to Robin/Subaru small petrol engines
- Smooth pivot surfaces for repeatable movement and positive engagement
- Straightforward to fit with standard hand tools in typical servicing
- Ideal service replacement when the original lever is worn, bent, or corroded
Typical Applications:
Used on small petrol engines powering site and garden equipment, including plate compactors, trench rammers, generators, water pumps, pressure washers, tillers, lawn mowers, and chipper/shredders. Suitable for maintenance and repair tasks aimed at solving hard starting, heavy pull effort, or recoil starter wear in everyday trade and DIY use.
Also known as:
Often referred to as a decompressor lever, compression release lever, compression relief lever, valve lifter lever, decomp arm, or starting aid lever for small engines. These terms describe the same function: temporarily relieving cylinder pressure to make starting smoother and more controlled.
