Wow! Secondary throttle plates were not drilled on QF carbs.

Now just because someone made an illegal modification to their carb and got caught, some armchair computer jockeys want NHRA to change a rule that has been there for years.

The QFT SSR-780 does not have drilled Secondary Throttle Blades.

QF SSR-780 only come with holes in primary side T blades. I have 4 brand new ones in the box and they are all the same. Available if someone needs one.

Thanks
