Retarded timing will result in a more energy being put into the coolant and
less power to the wheels.
Advancing the ignition will result in more power to the wheels and less
energy being put into the coolant.
Sounds like your timing is retarded.  If the igniter is phased just a bit
different the timing will be off.
Hope this helps,
Rick
