Preengaged types dont have bendix, the solenoid return spring pulls the pinion out. Aren't original lycoming starters generally bendix types but people like sky tec supply preengaged as superior aftermark replacements becauuse bendix is a cheaper, arguably lighter but technically inferior method , indeed prone to jamming in the engaged position. Pretty sure the original reason for the starter warning was stuck bendix, but Im sure someone who actually knows the detail will chip in shortly...
