Summer Tuning? 120-130

Your engine bay gets extremely warm in 90 degree plus weather. This causes the fuel to boil in the line between the pump and carbs. This can force the fuel past your needle valves in the float bowls and flood the engine or cause a rich condition. It also leads to "vapor lock."

That describes my engine in this weather... Causes the idle speed to drop and run rough. I really need to paint my hood, it's currently black!(I got a new hood, one that's undamaged)
