I've got my Dad's Vespa right now as I told him I'd replace the speedo cable for him. He had the motor rebuilt a couple years ago and after about 100 miles the cable broke and he quit driving it.
I've got a few questions about the Vespa, if any of you can help out.
1st- what is the thing worth? It's a 65 or 63 GL, I believe a 150. Dad says 65 but the manual says 63. I can't find a vin number. Orig owner, paint, etc. New tires, tank, wheels, muffler, seat, speedo cable, rubber bits. 4000 miles and stored indoors. Tag on it (last registration) 1980. Does have a few chips in the paint.
Next, the motor feels flat to me. It used to be more peppy. I'm thinking it's running rich as the plug was a little dark. I've drained fuel, cleaned plug, inspected air filter (carb & filter appear new). The petcock does not seem to work. What is the adjustment screw on the back of the carb for? Maybe it just needs to loosen up?
Lastly what is the switch on the pod with the headlight switch, horn and kill. Seems to have 3 positions.
