new build no spark no start

650 cca battery at 12.2 volts nothing (no spark)
750 cca battery at 12.5 v. one crank worth of sparking.
750 @ 13.4 volts started a few times till it dropped. then no more spark.

seems to crank good with all batteries. maybe i need a bigger battery or better starter.its a stock mini starter.
