Ive been having another look at it just now. There is a small allowence on the play in the rotor arm though small.
- If i advance it all they way i get nothing (degree or two). If i retard it all the way the play will allow, and move the cap through its max allowence too, it will just about run (degree or so the other way).
While running its also spitting a lot of fuel out of the carbs (pumping acclerator jets a fair bit hence a lot of fuel) hence thinking the timing might be out, but it seams not to be the cam timing thats out as have checked as above.
Also got a small flame just this last time, so deffo timing on somthing is out i feel.
