very basic magneto to service…
try a new plug on the cold cyl.
measure ohms from plug boot to engine frame xpect 4-8kohms if coil is not defective
when was the magneto serviced to inspect for cracked coils bad condensers dirty points etc… lot of info available if you want to jump in and fix it free instead of paying $100/h plus parts…….. lots of help here and your only costs will be available parts if needed.
This could be as simple as cleaning the points associated with the bad cyl… front coil feeds the top cyl !!
here are a few docs to read plus you have tons of utubes to fix magnetos used from early 50s to late 60s print this manul
