[QUOTE="Pappy, post: 491272, member: 3278"] [size=5]If the upper crank seal is leaking it will leave a visible trail from below the flywheel all the way down. If the lower crank seal goes it normally will really affect the running quality at idle. In fact both the upper and lower can affect idle quality. If your engine idles well you have a well sealed crankcase. Change fuel tanks and eliminate the tank. If you think the fuel pump is not pumping enough simply squeeze the primer bulb! The engine should pick right up and go. Let me ask you a question that I want an answer to. When going to WOT does the engine initially reach WOT then sag back down a bit? [/size] [/QUOTE]
