Thread: Honda Tin Tank won't start!

Hello all. Hopefully someone can give some good advice.

My old tin tank 300 has been sitting in a shed under a tarp for a couple of months. I decided to take it out for a quick drive, because apparently it's not good to keep them not running for extended periods of time. It went alright, rode it up and down the road. I was bringing it back in and riding down a short hill and it spluttered and died. Now it won't start. It has enough fuel, I've wiggled the spark plug and it doesn't seem to be either of those things. The starter motor winds away fine, but it won't fire up.
What's possibly wrong with it?
