May not be carburetor related.  Have you tried to isolate the missfire to any particular cylinder?....Cliff

i took the idle tubes out and went 0.43 on them . still had a miss  then went 3 turns out so far no miss when hot . what i cant figure out it i used to have the mixture screws at only 2 turns and it would idle fine. it seems like the engine wants lots of idle fuel
