Found a couple of places for the ignition stuff, don't really have the
time to drive to Staffordshire ATM to find a carb gasket or jets etc....
Hoping there's an online place that does Zenith carb spares but given
Zenith's carb numbering scheme (it's a 24 T2) I can get an awful signal
to noise ratio from google as it will pull up everywhere that does
Zenith stuff and not just the obsolete specialists.... finding it hard
to track down.... anyway I'm hoping that I can do it without needing the
bits....
