Lots of old Pentas have both and alternator and a starter/generator. Generally both belt-driven. A common setup was to use the alternator to charge the house batteries & run operating loads, while the DynaStart was dedicated to charging the starting battery.
I wouldn't let the engine kill the deal, since you know what you are getting into. Worst outcome, the repair estimate is high enuf to justify a repower. Better outcome, you get several years out of it & repower at liesure. Best outcome, damned thing runs forever.
