QUESTION: im not sure what the wro is? i did check all the coils last night! i had great spark.
Answer the vro has a hose that connects to the block...check that...when it stalls have you hit the choke to see if it picks up??? if it does then it is a fuel problem...if not, put a timing light on it and run the engine till it stalls, did the spark stop?? that engine has a stator that has low speed charge coils and high speed charge coils...
the low side may be ok... a peak volt meter will tell you the output...low side, 40 to 120 volts, high side 175 and up...
