Is the woodruff key the cog on the starter motor.

No, its inside the flywheel, it stops the flywheel from slipping on the crankshaft, they can twist and cause the ignition timing to be out, easy fix, just remove the flywheel and you will see if the key is twisted or bent, quite possibly even sheared completly

So are these the only 2 options or is there any other bits that could possible be at fault.

Just so I have all the options when it comes to Tuesday.

Well, I personaly dont think it can be anything serious, if the ignition timing is out it will be firing before the piston reaches the top hence it not turning over, you could try taking the plug lead off on that side and see if it turns over. If you need help when you are there, pm me and I will give you a contact number

Surely if the timing is out it will effect both cylinders, so taking the plug lead off on "that side" wont help anything.

 

On a belt driven machine its very unlikely to be a sheared key, but not unheard of.

 

 

I would still look inside the rocker cover first, its so easy to do, if the valves are ok then at least that can be discounted.

 

Just a quick thought. When it locks up, does it need to be turned backwards a bit to free up, before continuing round by hand?

Is taking the plug lead/leads off not worth a try then??????? I have had a number of sheared/semi sheared keys on belt driven machines over the years, one exceptional example was on an Estesia brush cutter where even the variable speed belt snapped as well as a sheared key when the guy ran into a tree

Sure, of course its worth a try, its easy to do. Its a question of quite what it will prove, but it may help to diagnose.

 

I still think from the OP that the problem is caused by the Right cylinder, so I personally doubt its ignition timing, but thats just my opinion.

[Tyz05]

One other thing, could be possible that the float needle is stuck causing excessive fueling or flooding of the one cylinder. Just a thought and probably irrelevant due to the fact the OP hasn't mentioned fuel pouring from the spark plug hole.

If you put your hand over the air intake to manually choke the engine you can feel the the normal suction. Just fort this might be a handy bit of info to help with any ideas.

Managed to grab two secs today to adjust the valves. Fired straight up. Glad if was that was an easy fix.
