SMS/SMR power spring starters are ideal for smaller engines working in tough conditions. Designed for engines from 0.6L to 4L displacement, they are perfect for easy and safe hand starting. The SMS/SMR series have the advantage of using proven SS/SR components including nosepiece, winding, trip and pinion assemblies. With a manual engage and trip mechanism and detachable crank wind, the operator can choose exactly how thestarter performs.
Using a power spring (rather than a disc spring) makes the body of the SMS/SMR range shorter and lighter. This allows it to be fitted to a wide range of previously incompatible engines. Fitting takes a matter of minutes, and operation of the spring starter does not require any special skill or strength.
