most motors have a stall current rating or on A/C compressors the call it a locked rotor rating
my A/C unit has a LR of 57 amps, and its going to take that 57amps at 120 volts for a few micro-seconds to get the motor/compressor to start spining
a 2hp air compressor could conciveably have a lock rating of 100amps, you are not going to get even a 50 amp surge from only one finding of your generator
so even if it poored all 25 amps into one winding, the voltage is going to go low, no way is it going to break the lock rotor amps to get the motor spinning
on only ONE winding
your buddys bigger gnerator was able to supply enough power to meet the locke rotor and get it spinning, try putting an amp meter around one wire the next time you do your tests, it hast to be ONE wire the neutral or the hot NOT around the ext cord
and yes, if i did not want to open the genny head, i would look around for a different generator
