New engines may be problematic for a standard starter.

Once they have been run for a while, a standard electric starter should have no problems with the Saito 1.00.

One option is to "bump" your spinner with the starter already spinning.

Another is to increase the voltage on the starter to provide more power.

I've been able to start 50CC gassers w/o any problems when I switched to a 14.8v 4000mAh battery setup for my Hobbico High Torque starter. I'm in the process of doing the same for my "standard" Hobbico too.
