Of course your right JoergJoerg wrote:Timing should be 10 - 12 Degreee BTDC at idle with vacuum disconnected and going up to 34-38 at 2800 rpm.
7 degree seem too early, and cherry red headers are not normal - looks like to much pre-ignition to me.
It was set about 10-11 BTDC and ended up around 34-36 at 2,800 rpm
Headers no longer glow after the inital start up when we altered the settings..
Interesting the dip when secondaries come in. I can obviously get above the UK
