Steve,
I had the bright idea of running the Holley Adjust A Jets in our SCF race
Tiger.
It worked fine on the dyno.
However, on the track the Adjust A Jet plates caused the engine to stall
under hard braking (i.e. every turn). As driver John Morton told me, "You
took something that didn't need fixing & fixed it & now it really needs
fixing."
So, while everyone else went to a dinner party, I was back at the track late
Saturday night swapping carbs & rejetting. That was the last time I messed
with those plates.
Which brings me to this question: Have you used these before in an
Autocross?
