Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Hi all can anyone help me, i am currently re-wiring my Dragonfly and converting it to 12v, at this time i have brake light and horn working but no head lights, do i have to have the engine running to power the head light or do i have a fault somewhere.
Cheers Kevin..

Kevin,
          If you have followed the Dragonfly wiring diagram, the stop light and horn will be working because they are wired direct to the battery. Everything else (headlight, sidelight, taillight and ignition) is wired via the main switch. To check out the wiring, start by removing the feed wire from the ignition unit and connect it to a low wattage test bulb. Turning the switch clockwise to the first position should cause the bulb to light (this checks that you have power going to the switch). Turning the switch to the next clockwise position will give you a headlight. Turning to the last position will give you sidelight. Check by connecting the test bulb to each wire in turn. Poor connections can often be traced to bad contacts on the main switch
  Turning the switch anti-clockwise from the 'off' position gives 'emergency ignition' (this is self energising so doesn't rely on the battery). The last position anti-clockwise gives parking lights only. You should only be able to remove the key when the switch is in the 'off' or 'parking' positions.

  Hope this helps,
                             Eddie.
