Cardellino front sprocket removal

Trying to replace the front chain sprocket. Got the nut off all right, sprocket is now loose on it’s shaft, but can’t get it passed the mag./flywheel casing. Do I have to dismantle the timing side of the engine, or am I missing something obvious? Thanks

H Jack,

I dont think I ever did this on mine. Can you post a photo, it might jog my memory.
