Default Johnson 30. Runs fast, dies

Trying to solve a problem from the end of last season. I've got a 91 Johnny
30. Cranks easy, runs up high RPM really fast. Dies.
Any ideas? The weather is getting nice(NC), got the itch.
Thanks

1. Fuel delivery issue - pump?

2. Thermal intermittant in ignition

Both easily home testable but if I have to walk you through *how* you really
need the boat shop.

Sound like a fuel problem. It has enough in the carbs to start and then the
rpm picks up as it leans out until it runs out of gas. If it' won't start
right away but will after it sits for a few minutes that would tend to
confirm it.

Leaning out. Check your carbs and fuel delivery.

Carb problem. Time for a cleaning/rebuild.

Consider the carb. vent. I created this problem once when I made a new
gasket. Seems like I forgot one tiny hole (which turned out to be an air
vent allowing equalization of pressure in the bowl). If this vent becomes
clogged, the fuel going out creates a vacuum and shuts it down.

Sounds more like an airleak.
