Starting a Teletype sync motor question


I'm using a 50Hz, 3000rpm 1/12th HP Teletype sync motor on 60Hz,
for 3600rpm in a rotary sync gap.  I tried connecting a 7uF to 30uF,
cap across the blue and red wire for starting, but it won't start this
way.  Yellow and blue are connected to the line.  I then touched the
red and blue wire together with no cap for starting, this works better,
but the motor still often needs a push to get going, and it makes
clanking noises as the speed ramps up.  Once it reaches max
speed, I disconnect the red wire, then it locks up fine.  I've been 
using this rather awkward method for starting it.

I realize that Teletype motors usually use an external relay block
for starting, but different motors seem to be wired a little differently?

I wonder if the 60Hz on a 50Hz motor makes the starting a little
more difficult?

Does anyone have any suggestions or knowledge of the correct
way to start this type of motor?  Or maybe the motor has an internal
