1990 Johnson 8hp J8RESR
Here is the backstory if you care to read: http://www.marineengine.com/boat-fo...0-8hp-Johnson-idles-but-no-wide-open-throttle
I've basically done everything to this motor, but it's still not right. I was going to break down and take it to a shop. When I spoke to the guy, he didn't hesitate at my symptoms and said it's bad a crankshaft seal causing extreme lean conditions. Sounds plausible to me since I've never been able to get it to run even close to "right" without backing the needle valve WAY out (instead of the recommended 2 turns), but then, it just leads to extreme flooding.
Does this sound like a reasonable diagnosis? Is there a way to test this without pulling the top apart?
How difficult a task is replacing the crank seal? I've seen a couple of videos showing some suggestions on replacing it. Seems pretty doable.
thanks all for the continued help!
