Outboard not starting.

Worse than using old petrol is using a petrol/diesel/2-stroke oil mix…don’t ask how I know but it took a while to work out what had happened..duh!

Fresh Fuel, new spark plug. Bet it starts.

If it still doesn't run, check for spark and if there's spark clean the carb.

Whatever this is it will be trivial.

It was the spark plug. Replaced and started immediately.
