And this returns
x: 3 carryover: 1
x: 2 carryover: 3
x: 1 carryover: 6

Done!
Also, I realized that my final code may be tough to decipher now.. A
nicer way to write it would be (the functionality is still exactly the
same):
def recursfac(x,carryover=1):
print 'x:',x,'carryover:', carryover
if x > 1:
carryover *= x
result = recursfac(x-1, carryover)
else:
# done with recursion, start our way up
result = carryover
return result
