I have Vespa LX 50 4T 4V 2010. I am experiencing some starting problems. Last year I had an accident with it on a dirt road, but the damages were only cosmetic. After the repairs its been starting pretty badly. They had somehow got the carburetor heater wire disconnected during the repairs and I thought the problems were caused by that, but then I got the new wire (the order took 50 days to get here), it didn't improve. The problems continued. Now the problem has advanced, when it try to start my Vespa with the electric starter nothing happens (engine is cold). Okay, then the kickstart, it starts but when the primer turns off, so does the Vespa. After few times of doing this I get going, but then the Vespa doesnt take any revs and does 15 mph for about a minute, then when the engine gets warm, everything is normal.
It had the carburetor replaced, but nothing happened, also fuel mixture and idle is ok.
The importer and the maintenance guys are running out of ideas.
Any ideas? Thank in advance
