I got an PX200EFL engine in my beloved Vespa 150 -61. I've run this since -95 and has been working perfectly. A couple of days ago i couln't get it to start.
There's no spark on the plug or voltage going through the spark plug lead. I've measured all the wires going into the coil and only the one on the left side (form behind) seems to have any life when kickstarting it. It worked perfectly the day before. When it comes to the electric I'm quite stupid to say the least. I've been told it's either the coil or the pickup by some friends of mine. But I've also been told you can usually notice some time before the pickup gives in on the engine. The engine was running smoothly as usuall the day before?
Got any tips on how I can check if it's the pickup, coil or anything else?
