Default differences in timing between points system and CH ign?
Engine older Echo 40cc, I have never run it. Rotor on taper 7/16" shaft.
I have trimmed magnets off the rear, shortened the forward steel taper and reduced diameter to 2" thus far.
The rotor had factory cast marks T for TDC (verified), arrow for rotation direction, and a 'M' mark at 32 degrees BTDC.
My question: Would the 32 degrees indicated for points system be my guideline for setting the location for the magnet installation? Is there a time delay of some degrees in a point system that would not be present in say a CH IGN type ignition? Reading indicates that alot of these small engines operate with settings under 27 degrees.

Uncharted waters, one rotor, ask directions before drilling useless hole
