is there a way to test a stator without running the sled
Yes, since most of the time when the stator fails, the sled doesn't run. All you need is an DVM and what values across what wires.
Post up make/model someone will have the numbers.
was the machine running before you started the rebuild / did it have spark ?
I would put it together and caller a day
rave valves are very clean, top end rebuilt/new crank seals, 130 psig compression in each hole, carbs clean, new vforce reeds, new plugs and wires, fresh fuel, unplugged the dpm and tried, no difference. Tried a buddys dpm and dess key, no work either. stumped...
