93 Civic Timing Belt Problem

I change timing belt before it broke. Car parts guy gave mee the "Correct On" Put it in and can't tension up. Found out its 106 and not 104 teeth. All I could find in town was a 103 teeth belt. Went on tight. I cant get the timing set so wonder it its because of the small belt (103 instead of 104) or off one tooth on the cam or crank. Car runs but no power.
