When the wait to start light went out she just wouldn't start. When you cranked it, lots of white smoke, would almost catch and sound like a flooded gasser. After cycling the ignition several times, it finally stayed running. Really rough until I got the RPM's up. Got 11,000 miles on it, totally stock. Is there a re-flash I need or something. Do have 4 oz of MMO and 12 oz of PS silver in the fuel.
