My also sounds like is trying but can’t get the oomph power to start… I’ll try your suggestion. When you depress the START button, are you also stepping on the accelerator at the same time?
Yes, because if the battery is not connected, there can't be any electricity going to the starter motor. The ignition switch needs to be on, because otherwise there will be no spark, therefore the engine won't start
My moped died on me battery is fully charged no problem it won’t electric start anymore I have to hit the solenoid for it to start is the solenoid the problem?
