Thanks Fred. If you ask me I've always thought the damn things were back to front but they will only fit one way round.But there is definitely something binding but I'm not sure where exactly. It appears that when the rotor is tightened down the actual underneath of the rotor casing is fouling on something. But that does not explain as to why when I operate it without springs it shows me the full mech advance and then I put the springs on, rev the motor and it RETARDS !
Its got me.
