I really would have liked to position the engine forward enough to put the bearing carrier in front of the seat post tube, but the mount plate will not accommodate that much forward movement. To give you an idea of how far forward it would be sitting, the engine block would be up against the front down tube with 1/8" or so clearance.
Look closely grasshoppa........this is how ya do it....


One other important factor to consider is where your chainline is're gonna be running the chain awefully close to the rear tire. I'm running fat 2.5" Hookworms and the stays on my frame are larger in diameter than your Schwinns. You gotta get it right before you bolt everything down for good, so consider the size tires you'll be running as well. Just a little extra insight
