450 holley help

Float level(s), mechanical timing advance (too early?), vacuum leaks....that's my $0.02CDN...

Ding!, Ding! Ding! rear float was set way high, timing was too advanced ( forgot about the advance when it was set originally.
hopefully it will stop raining soon so I can get it out and see if its all fixed. if not maybe its time to pull those wipers and re seal the arms
