A bad diode is the cause of your problems. You will need to pull the flywheel cover from the engine and replace the wire that connects the 2 ignition coils for their kill circuit. When the diode goes bad you loose spark to one cylinder. That may also be the reason you had gas in the oil, if it was run like this for a long time all the unburned fuel in that cylinder was trying to push its way past the Rings
