I know this has been discussed before many times but I really have run out of ideas now
I am rebuilding an Atco kickstart 1948 12" It was not running when I received it,faulty coil as usual.
I have replaced the coil and the condenser whilst I was at it,spun it up with a drill,no spark at at all.
replaced ht lead ,still no spark until spun really quickly then really weak
,set points to 12 thou,cleaned and stoned so that are contacting perfectly squarely,any oil or grease cleaned off,insulating bush is on( pre adjusting cam type)
new spark plugs tried,out of desperation I had the flywheel remagnetised which made no difference whatsoever
Checked all earth connections
if I close the spark plug gap to 10 thou I can get a spark but it's still weak
coil primary is 0.5 ohm and secondary is 5.4k
any thoughts please,I'm desperate
