Honda melody deluxe - just stopped running, how do i fix?

Welcome to the board. Your first post and you're asking for tech help! I hope you're going to post an awesome thread as payment.
As with all spark-ignition engines, the main things you need are fuel and spark. The spark is easiest to fix, so check that first. Take the spark plug(s) out and see what they look like. Give the electrodes a good clean in between the gap with some emery paper or similar. Then, check that you've got a spark by putting the lead back on the end of the plug and earthing the body of the plug against the engine. Switch the ignition on and crank it over, you should see blue sparks on the plug. If so, put it back in and it's highly likely that she'll start.

If not, then look at the fuel side. Take the float bowl off the carby and clean it out, as it will probably be full of junk. Check that there is fuel going to the carb when you open the fuel tap. Then, reassemble and try again. Once again, it's very likely that it should now start. If you've gotten this far and it still won't start then report back. If it does start, you are now obligated to upload the video of it starting and running to the forum as payment for this thread!

To be honest, I've never had an issue with old fuel. He said it ran two years ago, I've used 2-year-old fuel with no problems. Even on an old fire pump which had been sitting forever, once I cleaned out the gunk in the carby it happily drank down the rest of the ancient petrol in the tank.

I do recommend taking the air cleaner off and spraying plenty of carby cleaner down the throat anyway though. Cleans it and does the same job as easy-start as well!
