Hi Mike900
Thanks for your questions; the plugs are always dry after it eventually runs, usually black and sooty, but I put that down as needing the choke to start it even when hot.
The timing question is interesting because I did fit the a new Boyer-Brandson ignition unit and after a weekend of attempting to get it to run & tick over I thought that the timing may be out because since fitting the new ignition unit the bike would still not idle (I fitted this in the first place because the engine was lumpy, difficult to start and would not idle in the!)
So I decided to turn the magnetic rotor anti-clockwise (advanced) the ignition and the bike started up and miraculously allowed me to settle the idle to 1000rpm, I then decided to turn it off and restart, there was a little running on but she started at the first push of the button!! But then it all turned sour when I adjusted the pilot air screws, as she cut out & refused to start!!!!
I have not checked the cylinder compressions yet but the fuel is clean & new.
Any ideas will be well received
Cheers
