My secondaries were not opening! (Qjet)
I had a crappy time at the track last time. Car seemed to drive fine but I just wasn't getting the times I normally get. 
Here is the problem with testing at the track: You are going all out, things happen too fast, you don't have the luxury of hitting it from a cruise, easing off, you know really testing to get a feel for what's going on. But most important, with my helmet on I can't even hear the engine.
OK, so a couple of days later I go for a drive and with much anticipation pull onto a long freeway on ramp, and I hit it....... and (almost) nothing!! Hey, are my secondaries not opening? 
I have a fairly new Edelbrock Qjet replacement carb #1901 and it runs great. So today I take a look at the carb, and I can't press the secondary flapdoodles down (you know, whatever those things are called). So I look all over the carb for that secondary lockout thing and I can't find any secondary lockout thing, and I play around with the flapdoodles some more, and press and press and finally get them to go past the obstruction!! And they don't even come back up because a little itty bitty tiny screwlike thing is in the way!! It's not a screw, it's a pin, so I tap tap tap it back in and I think I am now good to go! 
Here is the carb after I freed up the secondary flaps but the pin is still in the way:
Here is a close up of the offending pin: With the flap laying on top of this, the secondaries would not open!
Can't wait to go out for a test drive.... vroooooom vroooooom!!!

The flapadoodles? That is a new one. The secondaries were probably opening you were just not opening the air valve. No air was entering the carb. Fix the flapadoodles and you should be burning rubber again.

I think youse guys are missing something baaad here. If this pin falls into the engine there goes the engine. I would replace it with a new one or glue it in or something to make it piston proof.
