To answer your question Garrett, no that exact scenario has never happened to my knowledge. BUT, a close acquaintance of mine was at a Divisional race a couple of years ago and was "spot" checked. The Tech Man wanted to see his carb and he complied. The carb on his combo was the ONLY number listed for his combo and (in fact) was the original carb for the car. Tech Man measures carb, carb comes up WAY (WAY WAY) too small, Tech Man wants to know why his carb is so small. When acquaintance tells Tech Man that it is the original and correct carb, the Tech Man doesn't toss him but tells him not to come to another race with THAT carb on the car.

Now, sorry for getting long-winded but the reason I wrote this is I was having a conversation with another acquaintance of mine yesterday and one of MY combos came up. Now, said combo will run MUCH better with a smaller carb on it but the original, correct numbers carb (I have it) is a big carb. The problem is that the NHRA throttle bore and venturi spec are for the small carb.
Do I run the "correct" carb or do I run the "in-correct" carb with the smaller specs? If I use the "correct" # carb, I take the chance of being tossed for too big a carb. If I run the "correct" spec carb, I take the chance of being tossed for too small a carb. In a situation where the guide contradicts itself, I really am not sure just how the chips might fall.

Now when you're thinking of the correct answer remember, I'm the guy who was tossed at Indy once because my heads looked "too stock".
