Easy "fix" for starter kick-back

When my 493", aluminum headed 12.8 to 1 motor gets hot, it just stalls the starter on the first try, but usually spins it on the second try. Sometimes. it's to easier to start if I spin the motor with the starter and then flip the toggle switch for the ignition to light. I wired in a cut out switch to the ignition box using a relay.

I heard guys with roots style superchargers do the same thing, but in their case to avoid blowing the blower off the top of the motor. Could be. I never had a blower on my car.

My problem is (was?) exactly what you describe it would stall out the starter first try then fire up the next try; it spins the engine over plenty fast. I got really freaked out a couple times it was so bad I heard the starter teeth grind that was my "F that SH**" moment lol...
