DQ at Reading

[Larry Hill]

What happened to stock 1778?

[Joe Santangelo]

My teardown was complete and the carb, engine and head all passed. The engine was being reassembled and one of the tech guys noticed holes in the secondary blades of the carburetor that has been checked three times in the last 5 years and countless times when the car owner himself raced it. After the Williams DQ at Indy it never crossed my mind to even check mine seeing how many times that carburetor has been inspected already. Tough DQ to deal with when the National Tech director tells you he knows it does not enhance performance but has to DQ you. But, it is clearly in the book.

Just because you have been inspected before does not mean you are legal. If you run a carb let my misfortune help you and check those blades with your own eyes.

Things like this don't help their reputation any...

If there are holes in the blades. It's getting a fuel signal.

When it is idling or when the blades are vertical?

I think we are all missing the point here!

[Alan Roehrich]

Holes drilled in throttle blades on carburetors are simply to allow the throttle blades to be closed enough at idle to not expose the transition or intermediate circuit, so that excess fuel is not added, and idle mixture can be fully controlled by the idle circuit. It merely allows the carburetor to idle on the idle circuit. The holes are NOT there to expose any of the transition, intermediate, main, or other enrichment circuit to any signal, but rather, in fact, NOT to.


In the case of the Holley carburetors, they are in the secondary plates to allow the secondaries to move some of the air required to make the engine idle. The ALLOWED modifications to the Holley carburetors INCLUDES replacing the secondary metering block or metering plate with a different plate that MAY include an idle circuit. The rule in question was there to prevent, for some reason, the use of four corner idle circuits and adjustability. Currently, when using a secondary metering block or plate that includes and idle circuit, you are supposed to block the idle mixture adjustment screws with plugs.

Appreciate your transparency Joe. Best of luck the rest of the season.
