Engine turns, but only while peddling

I had something like that happen when I was working on my new bikemoped. I tried riding down hills to get it started. Turned out a wire got disconnected. If engine doesn't turn over after peddling, it's most likely electrical.

If its the very first time you have fired this engine into life it will take a bit to fire up.

When I first built mine I had to peddle all the way around my block.

I was knackered after peddling all that way and was about to stop and wonder what I did wrong when it sprang into life.

You arent getting spark or fuel.

Yeah, I noticed first day I was riding it, it was **** to get engine started. Now it starts easy, even with choke off completely cold.
