For the Holly sniper throttle sticking you have to change the throttle bracket on the throttle body, Holley sells it, it’s a know problem but cheap easy fix, had same issue with mine
This 56 is a true owners dream and as is clean as this lady can be, but I know she is not perfect at 67 years of age. But give her, her do, for I am an old car builder for many years and this ride has so much to offer for what she is and what nice a ride to see. For things are easy to fix, gust like nodice333 said below. It's all cool.
That sniper isn't wired right, It should have constant power at key on while cranking over.. The sniper screen should not flash while cranking the engine over. It should stay on throughout the cranking cycle.. Also go into the settings on the sniper screen and pull up "monitor" that will show you temp, afr, all that sheeeet.
