Yes I can relate to that, this is why I got all the PT motors, the bloke wants the bases to fit 4 strokes on, I don't know where he is getting all the 4 strokes from. He was asking if I could get him any non rusty Victa bases but he knows that I need all I can to fit the PT's on.
Good job on the Vortex, did you just polish it. For some reason I found the Vortex mowers very hard to move, no idea why, only thing I could put it down to was that people could not see the motor
