Ran the quadra 75 today with the 24-10.
I set the low end at 1 and had the high end from 3/4 - 1 1/2 best RPM was 6200. The surge/quick 150-200 drop occured every 45-60 seconds when ran wide open but would last for a second. The engine fired every time, never stumbled or cut out. I did not see any air bubbles in the line or see any fuel around the carb. What is a strange is the low end was just as good at 1 turn than at my orginal setting of two it never seemed to make a difference the transition was still flawless...
