I'm amazed you didn't experience some type of exhaust of intake backfire attempting to start your engine with a sheared key.

Well the last couple of times i tried to kick it over before i pulled the casing i got a couple of mighty kick backs from the kickstart!Just about launched me over my house! :-D

rumpelstiltskin:
Well,got the woodruff/flywheel key fitted and still wont fire up,spark plug still not getting fuel,im convinced about that.If the reeds are wet and with the manifold off i can see the reeds are moving so fuel must be getting there,and compression is fine!Im just on the verge of getting rid of it,it's getting on my nerves!I've spent a fortune restoring it and it can't even do me the pleasure of firing up,the sod!  :cry:

Podium Werx:
Hi have you tryed petrol down the plug hole if it firers then it could be seals or reeds

rumpelstiltskin:
Im just double checking everything before i go tearing the motor down again.Tested the stator wires.One of the readings was slightly high,the reading between the yellow and the black and red wire which should have been between 14.2-21.4 reads 25??Would this cause a problem?All other readings were fine.Im just trying to rule out maybe the spark not being strong enough under combustion conditions.Timing is ok too.Fuel is now getting to the plug.
