Pulled the Mess that was my Timing Chain....

So I was looking for the needle on my carb, where it does not have the adjusting screw like I've seen on all other Holleys, but rather this nut/threat combo that hooks my fuel line to the carb (found a PDF of a manual for Holley that appeared to be just that). I'm pretty sure that was the needle and seat....I provided a pic of the two pieces. Came horizontally from the side of the float bowl housing. It looked pretty clean (maybe a speck or two of dirt), but I sprayed it out with carb cleaner and dried it all up with an air hose before putting them back on. Didn't get to turn the engine over, since an earlier (inexperienced) class "tried" to check my valves. Some were screwed around with too far, so I had to spend my time trying to fix those to .12 intake and .22 exhaust, cold. Did not change any that were alright, just those that were obviously too loose. I will check them again when the engine is running for more accurate checks. If I turn it over and it's still struggling, I'm going to pull the float to check it, most likely tomorrow.

Below is what I thought was the needle and seat, with the thread and bolt that attached to float bowl area and to my fuel line. (Sorry for bad picture, my phone was just about dead) :
