740 running ruff, exhaust rich

Before quickly getting hot under the collar why don't you just wait to see how the case develops?
May be you should make some time to work on your manners and grammar skills while you are at it.
You obviously have been struggling with the English language since before 1972, and look at the results!

Are the plugs wet with gas? Chances are they are contaminated just like your oil--change both!
Usually "run rich" is caused by too much air which sends a signal to the computer to send more fuel which doesn't get burned so it goes into the oil and fouls the plugs
Look for an air leak!
The air valve is NOT supposed vibrate.

At this point I'd take a compression test to eliminate something serious like a valve problem. If the compression is OK, then you are looking at the cause of the misfire because this is what you have based on what you are reporting.
So far, seems like you have a problem with #1 cylinder...
