See that why people needs to post the engine info. I have yet the Hp rating fixed in my head when comes to the Kawasaki engine especially. I just done with a FTX00 engine but that one is over 30 hp but it was a DFI and not EFI fuel system.
True but generic is close enough for this one. When he checks for VAC coming from stator he will probably get little to nothing since he already tried a new regulator. If he gets 26 or 25 or 30 or 35...or if his meter isn't very accurate lol, any voltage that high means it's time to do some more digging into problem because it's prob not stator.
But yes, without model numbers, engine model etc, we are all guessing but at least it's educated guess for some of us.
