I would stop the karo syrup as soon as you get the Nutri-Cal which I hope is very soon! Sugar (Karo) gives him the quick spike in sugar but they need protein to keep it up. The Nutri-Cal gives a more stable form of sugar. I would give him a dime sized dose of Nutri-Cal 2-3 times daily as a preventative on the roof of his mouth, if he doesn't lick it off your finger.
Since some of my 8 week old puppies don't even have good teeth yet, I grind my puppy kibble to allow them to lick at the food all the while Mom is teaching them to eat. It may be that Mom didn't have the time to teach your baby to eat kibble. You can also mix a little milk replacement to the ground food for a mush on a saucer. I don't start weaning until 10-12 weeks, so this little guy lost important teaching time with his Mom.
You will have to keep a very close eye on him, it is a very dangerous time for him.
Good luck and let us know how he's doing.
