Were the idle screws removed as required?
If so they probably should have been given the option of fix the holes...
A 15 minute fix with a little solder...
Was that after all qualifying was over?
Were they DQ'd from class?
Or the hole event?

Kind of a dumb rule in my opinion...
Don't even see the secondary idle screws as a performance advantage...
Especially when the rules state "any internal modification allowed"...
Or did I misread that?
Can someone explain the advantage, I'm always willing to learn something new...

NOT the mixture screws - the issue was holes drilled in the secondary throttle blades. For which there is NO performance added. ZERO. The rule book says no, but the approved Quick Fuel carbs (SSR 780) came with holes in all 4 blades.
The idle mixture screw heads had to be "covered" to make them "legal".

Hey guys, a post I did not want to make. Dan Williams in his B/S 69 Nova was DQ'd from the race for a carb infraction, having two holes drilled in the secondary plates. The holes are drilled for idle quality, but NHRA says that is illegal.

I thought that rule was gone years ago. With Quick Fuel carbs be legal along with swapping out boosters on the older Holley carbs. I was shocked Dan was DQ'd. And for anyone to say booster swaps are not allowed, you would be wrong. I replaced the boosters on my Mustang when I ran the 735 Holley and they were deemed legal by NHRA.

I would think a booster swap would be a performance gain, not two small holes in the secondary throttle plates... go figure.

The real kicker hear is Dan has been torn down many times, the last time was 2019 here at Indy with the same carb and NHRA had no issues with it. These guys come all the way here from England to support NHRA and get bounced for a rule that should have been taken off the books years ago.

Its really sad that rules are not updated for consistency. Aftermarket carbs, other mods to the carbs are okay, but not to small holes that give no performance gain.

I applaud NHRA for tear down, there is four stockers with the heads coming off and dozens of Stock and Super Stockers getting Carbs and throttle bodies checked along with fuel injected cars have to give access to there ecu data... but come on, getting bounced for two small holes in the carbs, so disappointing.
