Can’t be taking off the flywheel every time I have to change or set the points. .
Going back to the days when “all” BS engines had points, ignition failure from component failure or maladjustment was comparatively rare – unless the points cover was not properly sealed and/or the machine was left outside during winter etc.
A Magnetron replacement is a nice neat solution using an original component but it shouldn’t be forgotten that as an alternative, an aftermarket transistorised points replacement unit used with the original coil is an equally reliable and maintenance free solution. I’ve got both a little used BS engined scarifier and a rotary cultivator, both fitted with Meco triggers some 30+ years ago. I regularly repair and restore Villiers F12 Sloper engines, mainly on Ransomes lawnmowers, and fit Meco units as a standard part of the rebuild: never had a failure yet.
The two trigger units that are readily available in the UK are Meco and Nova. I prefer the Meco as it’s a little more compact and may be fitted within many magnetos, whereas the Nova usually has to be fitted outside.
