Ok...well swapped over the power packs and found a loose wire! 
Wahoo! Bright spark on all cylinders now. Also changed the bendix - so all is good!<br /><br />However, She wont run at slow speeds - requiring a dab of choke every so often to keep her running. Give her a handful to open up and it tries to die - a dap of choke and va voom!<br /><br />Mixture I pressume? I assume that giving choke saving the day is an indication that its running lean?<br /><br />Do I just turn every carb adjuster the same amount?<br /><br />As always thanks ever so much for all the help!
