Here is one I found this weekend that I will have to put down on the check list!!
Got to the track and ran the heat -car ran like CRAP! I have been trying so hard to get in the top five this my first year and I am sooo close. Fuel pressure okay - timing okay - ??? Pulled breather off and the secondary needles on the Q-Jet were perched wide open. Had to unscrew them to realign and then finished 2nd in the B main and fourth in the A !!!! I finally did it even against the "cheater" motors.

I would be very interested keeping this thread going with some of these little gotchyas. What do you look for that is kinda odd??

Yeah, the tiniest little things can catch ya off guard... A couple weeks ago, about halfway through the heat race, the car started to act like it was going to stall out & die when I pitched it into the turns, but it would take off like mad just as soon as I made it back to the straightaways. It almost seemed like it was outta gas & just sloshin' over & not pickin' up in the turns, but I fill it full before every race... So when I pulled back in, we checked the cell and it was still close to full. After checking filters (clean), tearing into the carb (nothing wrong there), and even lettin' someone else's pit crew have a look too, we couldn't find anything wrong. I'd made the A, and I was almost ready to just go back out there and take my 50/50 chance of having the problem corrected or not... I sat on the end of the trailer for about fifteen minutes puzzling over what might cause loss of fuel, or what might make it feel like loss of fuel.

I felt like an idiot for not checking sooner, but sure enough, the fitting that holds the line comin' out of the cell was loose, and it was letting the line swing around in there -- so when the car went into the corners, it was throwing the weight of the fitting against the body & pinching off the hose.

<<Duuuuhhh>>

Interesting posts guys...
I have now won my first main (in a long time)and I can say it didn't come without a bit of anxious seconds. I had the carb begin to act up with about 7 laps left, after a lap it took off again. the float was just not letting fuel in. cleaned it up and took care of it. But, over the years, I have had many stories like yours, My best advice, keep the vents clean on your Holley carbs.

Here is another
Didn't catch this one till I had to pull the engine down AGAIN!

I relied on someone else to put in the freeze pugs on my 350. He just knocked them into the block so that they have the opportunity to rest against the cylinder walls and or move around to block water flow between the cylinders. Man I will let that guy know about that one!! It wasn’t hard at all to pull them out. But he amount of ticked off goes on and on!
