I don't know if you know this, but there is a thing called Youtube and it is the stuff of magic. It has transformed this mechanical novice into a master Vespa mechanic. After chiseling out and replacing the oil drain plug, filling the battery with acid, replacing an idle jet, putting in a new spark plug, installing a new oil filter, removing and cleaning out the carburetor, and changing the oil, my bike is up and running again. I can hardly believe it. *phew!*
I also want to credit all of you ModernVespa-ers who have given me advice over the years. You've made this journey so much easier. Thank you.
