Hi PeterW
The symptoms you describe are consistent with weak ignition or fouled spark plugs
Although there should be some residual spark at the points when you "flick" them, the condenser is there to minimise this. If it really is blue and fat, it suggests the condenser isn't doing its job so I suggest you try another and/or check its connections. A blue fat spark from the far end of the king lead when it is removed from the dizzy cap and held a few mm away from earthed metal is what you should be getting when you flick the points.
I have often found that points tarnish during layup, even new ones. Careful cleaning with a fine file, followed by a squirt of switch cleaner or a piece of thin card soaked in petrol will get rid of any corrosion dust you have removed. Let this evaporate a bit before starting.
