Well,
On my BBC 454 It appears I have one cylinder that is running lean. What would cause this? The boat has sat for 5 years and I have taken it on one test run since cleaning her up. I removed the Headers today and found #6 Cylinder on the header side pretty white. I pulled the plugs and found #6 to be slightly white. I didn't take note to how the plugs looked before the test run but I did spray some high temp paint in the header tubes
(got a little carried away with the paint that day) Would the water mixing with the rust and paint cause this to look worse than it is? I'm a little confused on how one cylinder can run lean. The boat runs great, no hesitation, bogging, smoke or pinging. It idles fine and accelerates smoothly. The plugs are old and need to be changed, as well do the wires but I doubt a faulty plug or wire could cause that cylinder to run hotter... can it?
any input would be very helpful,
James
EDIT: Forgot the pics, the flash might be over exaggeration the whiteness a bit. It was getting a little dark when I took the pics but I saw them during the day and they didn't look as white as in the pics
