Quick update.

After more tinkering and and replacing that seal she was running good and then the oil seal behind the sprocket went.

A total tear down and cleaning of the motor (plus everything else really) is the plan.

Why not just replace the seal from the outside; we have some threads on it?

ha, I on second thought it doesn't look too difficult. My concern is the next weakest seal is just going to go and so on.

It runs but take holding the revs at 2000 or so for a bit before it idles on it's own with out gas. It seems I have to give it a few revs quick once it turns over or it dies off.

And my clutch arm is extremely stiff. I can't push it by hand it it take lots of force with the cable which made trying to set the adjustment screw impossible. So I am wondering if the plates need replacing/unsticking or someone needs to peak in side.

I have these two part numbers 93102-35180-00 OIL SEAL and 93210-22298-00 O-RING from http://www.boats.net/parts/search/Yamah ... parts.html (26 and 27).

Any guesses on what may pop next? I am trying to do some reading on common oil leaks.

That countershaft oil seal is definitely replaceable from the outside. Also remember that it will leak even with a good seal if the countershaft sprocket is not secured properly.
Good luck,
Henry

I doubt your clutch issue is your plates sticking, have you lubed your cable recently? Are there any tight bends in it?

I would question seals "blowing", by that do you think there is internal engine pressure that is causing these seals to "blow"? I understand a seal leaking, and it does look like the clutch shaft seal isn't seated properly, but there shouldn't be any pressure trying to "blow" the seals. Also it sounds like your pilot jet circuit on the carb is plugged, starting on choke and having to blip the throttle above 2000rpm to keep it running, sure sounds like a plugged pilot.
