I had this once with a yammie Malta, some diddy had removed the flywheel and replaced it without replacing the woodruff key. I found it on the underside of the flywheel. No more intermittent spark and no more wet plugs!!

Disconnect your dead mans switch and try again.

I've tried the kill switch, but haven't had the flywheel off!

Ordered a CDI unit that I can return within a fortnight if It doesn't work.

Will have a look under the flywheel and see what like. Although, it's pumping water when I turn it on the cord, surely this wouldn't happen if the flywheel was slipping on the shaft?

Cheeeers

If the woodruff key was sheared you would still get a spark, if its a cdi unit all that your going to see underneath the flywheel is an exciter coil.Have you spun the flywheel with an electric drill with the plugs out but connected to the plug leads?

We had woodruff key snap on an Evinrude engine , key was in place but flywheel was not tightened down enough causing shock to the key which made it snap , even though it was tight it was then just enough to have the flywheel move around on the shaft a couple of mill causing the timing to be out . Just thinking when Sparticus earlier mentioned about them being bullet proof was asked by a mate to look at an old Tohatsu 5 (points ignition) he had the similar problem with the engine flooding , He dropped it off one dinner time ( lunch time if your southern ) so really quick i said ill have a quick look before back to work i said well use the wife's new plastic waste bin (shes out & wont know ), i went outside where me mate showed me the fuel ( took float bowl apart found float valve not seating proper got that back together again so i said right you hold the engine upright whilst i pull it over ,,,1st pull nothing ,,,,2nd Pull BANG , engine and my mate shot about 5foot in the air with me dtill holding the starter cord , engine & my mate crashed back to the ground , what had happened is whilst i was having me (lunch ) he had been trying to start it , petrol had run into the lower leg then when it fired it ignited excess furl in the exhaust causing explosion like a small mortar , lucky the engine was fine & ran for years without anymore problems we just had shell shock & tinging ears & wet feet ! worse still it had blown all the bottom out of her kitchen bin .
