ISuccess at last, I was using correct flywheel extraction tool , there is no room for a bearing pullers.
I took the bike to a engineering firm who i used to give work to ,they allowed me use of a set of gas bottles, acetylene is great to apply heat quickly in a specific area.
Heat on ,flywheel tool on and a few heavy thumbs of a copper mallet it popped.
Now off to find crank seals, UK is not an option for us now due to brexit.
Does anyone have the seal number to hand, my bike is 1974 I think the seal is specific to that year ,double lip seal with 2 springs.
How did I break it well, lets say I did not put much thought in removing it and used the inner bolts to lock it rather than wait to get the proper tool.

Hello
My 74ty 250 starts fine and will run for 10 minutes or so ok then when the throttle is opened it stalls like getting no fuel.
Carb out and cleaned several times.
Today it seemed to recover for a few moments when I pressed the choke.
Vent pipe is not blocked
New points and condensers, new crank seal on that one side only, must do clutch side next.
Whats left ,carb rubbers or gaskets, reeds
Had anyone this issue before.
