Well because it's closed I don't know that there's really a good way to measure the actual timing of the motor... but I suppose you could do a simple test to see if one motor has more timing than the other...
Any simple RPM checker would work... a prop based or LED based one like what you find in alot of the motor checkers/motor running stations now.
Simply run a motor with the polarity one way and take note of the RPM.
Run the motor the opposite polarity and take note of that RPM... if the timing is zero the RPM difference should be negligable... but if the motor has a significant amount of timing in it you should see a big difference in RPM.
The more change in rpm from one polarity to the other would denote more timing in that motor.
You could probably do the same test by ear... but sometimes our eyes and ears can decieve us!
