Tried starting the bike this morning and there doesn't seem to be any improvement. It would 'bubble' along like it was trying to catch (it acted like a weak spark) but again it took starting fluid and the choke seemed not to play apart. Once it had 'caught', restricting the air flow through the air filter with my hand significantly increased the rpms. Maybe I should also check the state of the battery huh? Incidently I noticed the fuel gauge didn't work until I revved the engine significantly and held the revs. That was a new one to me, Graham
