Hmm.
't was not an offer in that sense, but meant in good humor.
There is very little available to cater for your needs. It does not take a lot of work however to transfer your magneto drive into a CDI ignition.
RCexl makes conversion units for Zenoah engines.. Lacking that option, most chainsaw engines do have a second outgoing shaft, where a crude magnet holding disk can be attached. Something adjustable for the hall sensor to hold onto must be provided next.
It does not have to be pretty, it just has to do the intended job, and your conversion is good to go.
