<VV> carb rebuilding

[cfm]

good morning all.
I spend some time yesterday pulling that one carb off my 69 monza vert (with a 110/pg). I purchased the minor rebuilt kit from clark's (557L) and as I go through it, I have a couple of questions. This is my first time rebuilding a carb, I am capable.

1.) in the kit, there was a small bag with a new brass viton needle, seal and gasket. Inside the bad were two red gaskets, after pulling the float off and the viton needle, I only see one. However, when I look into the upper half of the carb housing. it looks like there is another one, or is this just an imprint of the old gasket? So why two gaskets? they appear the same in diameter but have different heights, one is thicker than the other.
2.) following the instruction sheet, and the shop manual to some degree, I was determining the float adjustments. I understand that the float is to be parallel with the carb housing and that when its is up the needle is to be closed. There is a measurement to be made with a ruler as to where the floats are, is this to be a specific dimension, or is this a check to insure that the each pontoon is at the same height?
3.) the float spring, when I took it apart the 90 degree bend in the spring was lodged in the slot on the bass threaded piece. In the shop manual one of the illustrations appears that the spring is resting against the brass stem. Which is correct, the way I found it when opened, or the way it appears in the "book"?
4.) the "bend to adjust" appears in the shop manual and with the instruction sheet. The tap is to put pressure on the needle to close, I understand that part. But when it comes to suspend in the floats, is there another "adjustment" that is required?
5.) on the backside of the float frame, there is a slender rectangular tab that is a part of the pontoon frame, when I removed the float I bent that tab a little bit thjinking it would help with removal, then I discovered you had to tap the rod out to get the float off. What is this tab for? If I bend it back it seems to play a part in how far the float hangs down. Any insight on that part?
thanks to all in advance.
going to miss Elkhart Lake today :( vintage races and car show and all three area clubs and their Corvairs!) have to work.
