Well I pulled the distributor apart today. Looked good, both mechanical and vacuum advance seemed to be working smoothly. Cleaned it up a little and put it back together. Still runs like a pig. Too hot and humid and too late to throw a timing light on it, maybe tomorrow. Only other thing I can think is vacuum secondary's. If they're partly open that would keep the idle up, if they kick in too soon that would cause a bog. Maybe something else to tear apart. It's always something.
