Older Merc 4.5 hp won't start

[Markd]

This motor sat in my shed for about 4 years and when it was stored it ran just fine and super. Took out to use it and no start. Got fresh gas and gas seems aok. Seems like ignition took a flop.

Not sure of year; very late 70's or early 80's - 1 cyl.

Another question; where do I get parts for this if needed?

Ideas?
