You still have some pretty nice machines hiding in those pictures there!!!!
I forgot, I do have a Powerplus in the form of a side pull full crank self propelled.
Engine started briefly when I first got it then it made some popping sound, stalled and wouldn't start. It's been stored since (five years). SP system needs work, mainly the cable and belt pulley by the looks of things.
A couple of others I peeked at with the phone camera, including a better look at my 72 VC Auto Drive with the SP removed and carby troubles.
Silver streak and Corvette work but SS doesn't stop and Corvette runs ok but is loudish and has bearing noise that gets taxing as you mow.
