1973 Vespa

What is the oil to gas ratio? This is a "Ciao" ( 1973 Vespa ). It stalls after running about 2 miles.

Mixture 50 to 1. or 2%. I mix a can of gas using the gascap measurer full of oil and a leter of gas. The carb is in need of cleaning most likely. bruce

And if the carb clean/rebuild doesn't yield any results, pull the fuel line to see what kind of flow you're getting.

If you get good flow and it still shuts down after a couple of miles, then it may be that your ignition coil is overheating and needs replacement.

Let us know how you make out.

It sounds like a fuel flow problem. Loosen your gas cap and try it again. Jim.
