I bought the scoot, seduced by it's apparently stock 6.5 BHP and with looks that are very similar to the Honda Spree with the intention of seeing if I could get 40-45 mph out of a standard 50cc moped. As soon as the weather gets better, I'll give it a clean and post some pix.
The problem is that after a week of standing, it won't start unless I spray something like brake cleaner or carb cleaner into the spark plug hole. Then it'll fire and normally will start. When taking the plug out, I can see it's wet. Once started, it runs really well & idles well with no misfires, it revs easily without issue. Before I bought it, the scoot had been in storage for a number of years, when I drained the tank into a glass jar the fuel went cloudy after a few minutes so am guessing there was a fair amount of water in the tank.
The engine runs faster when first started so am guessing the choke is fine. I've cleaned the carb, drained the tank and put in a new plug. Next day, it'll start fine but leave it a week.. As it runs ok after it starts, I'm assuming the fuel is not contaminated any more.
I'm assuming that this is not specific to Suzukis so may be of use to Honda owners, any thoughts for things to check or try would be gratefully received.

Update:
I did some more searching online and came across this post on Moped army...
"i own a suzuki ae50 and i got often the same problem try shoot air in the upper right hole in the carb with a compressor if you got one if not, try putting direct gas in the compression chamber thru the spark plug hole. and kick start it with the air or gas. hope that help"
Looks similar to my problem. I think the 'upper right hole' he's talking about is where the float chamber vent goes. For some reason that pipe is about 2 feet long and ends up in a frame tube. Maybe so that you can blow in it?

Sorry for the non Honda post, but thought it might be of some use / interest.
Thanks
