Hi,
C15 trouble again - sorry. I am getting a persistent misfire at all revs. I have changed the plug (NGK B7ES 23 thou gap),plug cap, condenser. Points ignition fitted with a regulator/rectifier from Rex Caunt racing. I have set up the points to the correct gap and set the tappet adjustment (although I struggled with getting the piston in the right place). I'm not sure about the ignition timing - I can't see how the procedure described in the manual (knitting needle down plug hole etc) can be very accurate. Any ideas would be gratefully received.
Phil
