im sure someone can help.. but i gotta ask you the same questions 50plus asked AJ..
These little bikes come in many flavors. Sometimes you gotta hold a lever and push a button and pedal backwards before you can start an engine.. Sometimes you just pedal.
So go read those questions and then provide all the information you can, including anything else that might help someone diagnose the problem.. like how things are normally, what happened that may have caused things to change, etc.
and i don't mean to be offensive, but use some punctuation. You are not talking to people.. you are writing. Communication by the written word is already difficult enough even when good spelling, grammar and punctuation is used by both parties.
People do not have the added benefit of watching you and your gestures and so can interpret your words and see the pauses in your conversation. When "talking" here about technical stuff, it's even more important to be as precise and as clear as possible.
Eveyone who hangs in here wants to help (and many actually can help :-) Do what you can to help them help you.
