I learned this the hard way when becoming "educated" in doing 7a and 3b 
timing belts - the Bentley rule of thumb is being able to twist the TB 90 
degrees between thumb and index finger...as Ned of IA later pointed out to 
me, it's how easily you can do this that makes the difference - too loose 
and you may skip a tooth, too tight and you'll hear the "turkey gobble" 
from the front end.
