HiOctane said:They work great on older chain saws.But you have to get one with the" right color".For a chain saw ,you need the BROWN one and the brand most commonly used is Atom.Some models fits on 4 stroke,others on lawn mowers,etc. depending of color of the module.
What do you suggest for hi speed saw ?ozflea said:This particular module has the hi-speed cut-out and is unsuitable for high reving saws.
