Its just wierd that it runs fine and then after awhile it starts trying to die at a stop.

So mixture screws all the way in and then back out 1/2 turn ??
Ned, screw them in slowly watching vacuum or rpms; the vacuum will drop and the rpms will drop as it leans out. Start screwing them out until you get the best vacuum and/or highest rpms at idle. If you go too far out the rpms and vacuum will drop again. Find the happy medium, highest vacuum or rpm. You'll probably end up 1.5-2 turns out, sometimes a bit more.

Do both sides a couple times. If they're way off the idle speed may go up enough that you need to drop it back with the idle speed screw, that's fine. Also, if that carb has four corner idle circuits (idle mixture screws on the secondaries also) then do the same with them.
