Different solutions to each of these. Plugs will appear black and could be damp and smell like gas if fuel fouled. Black and oily will be more problematic to solve. |
Correct.
Do not try to correct the condition you have with a hotter heat range spark plug.
For a street car, one range colder than factory spec is generally enough.
What camshaft specs have you got?
Give the idle air bleeds a shot of carb cleaner first and reassess.
