Modern Vespa

Hi, I've had my 2011 LML PX125 for 9 months and it's run fine. On Friday I used the 'reserve tank' fuel supply for the first time. On the way home I filled it up. Today it kept cutting out without warning. It would be running fine, then cut out. At first I went about 2 miles before it cut out first. But now it does it after a couple of hundred meters. I'm assuming there must be dirt in the fuel line. any suggestions on what to do about that, or what else it might be?

I'd suspect you've sucked some crud into your jets or fuel filter. Check out the link on how to get to them to clean them out.

thanks for that. I'll give it a go.
