Heavens above what next !! One not for the forum I feel such an idiot.

The new coils arrived today so i decided to fit this afternoon to find a fuel leak...from the primary drive!! Friday when I could not get the bugger to start I left the fuel on by mistake. I guess its filled up the engine which has leaked into primary. Gearbox too? Very smart not having an engine drain plug eh ?.

Looks like it might be in the oil pump too.

Very depressed about it !!...especially as the house here has an annex attached to the house I use as my bike garage. Does the house stink?

New mk 2 carb needle ordered with float. Guess ill just empty everything in gearbox and turn the motor over a million times. I know you said this had happened to you. 

My next bike might be a Honda 50 Cub.

From what I have read, the Boyer does switch off if the engine is not running to protect the coils from overheating.  What you are seeing on the ammeter could be correct.  I have been considering spark plugs too.  I am goIng to try projected tip plugs.  There is plenty of clearance from the piston and it puts the spark further into the combustion chamber.  If that works I was then going to try Iridium fine wire versions of the plugs.  You are already using fine wire Champions I think.  A projected tip platinum plug works a treat in my Venom and a Champion L3G has improved the running of my MZ TS250/1 a lot.
Smokey Paul had problems with the enrichment system at one time, passing all the time.  You seem to have the opposite problem if the plugs are dry.  Might be worth unscrewing it and checking it isn't blocked for some reason.
