Hope someone has some thoughts on this.
Started my (on loan) mariner 4hp the other day, first time since I've had it, it ran for long enough to let me untie the mooring lines, then just cut out and now refuses to start. Changed the fuel when I found there was too much oil in the mix but still no luck.
Fuel is getting through because I can see a film of petrol on the surface of the water as it comes out of the exhaust
Tried checking the plug and could see a spark, so now I'm lost.
Any thoughts ?

I am seriously no expert on this, but having had the same problem recently, don't discount the obvious.
I flushed the carb and changed the plug in mine and it's fine now.
Suggest you try to change the plug anyhow. And flush the carb, regardless of your fuel flow theories.
But if you genuinely have fuel and spark - all that's missing is air perhaps?

Hi Bob
Sorry, should have said, the breather on the tank has been checked and air is flowing into the tank, but is there another air intake maybe ?
Not used to working on outboards
Also, any idea if the engine stop button is supposed to be held out by a kill cord ?
I've seen that on some engines but this didn't come with one
I'll have another go on Monday and change the plug too

Just happens to be the area I'll be looking at this afternoon, thanks though, new plugs on order so I'll update if I manage to get it going
