Hello all
I'm trying (unsuccessfully) to fix a timing gremlin. I currently have the dizzy set to 4 deg. BTDC as I run mainly on super unleaded, but I still get pinking under (hard) acceleration.
I have just fitted new plugs, checked the timing etc.,, so what am I missing?
BTW the car has n Aldon Ignitor, so no worries with points or the condenser.
Thanks in advance

could be a weak mixture.
What plug gap are you using?
I take it you are checking timing with vacuum advance disconnected and plugged?
It could be that the mechanical advance springs are weak or even broken allowing the ignition timing to advance too quickly. A good standard 2 litre pinto should be able to run at 6 to 8 degrees on a standard dizzy on super unleaded.

Weak mixture? Hmm. good point.
I'm using the standard plug gap, i.e. the gap the plugs came with
As for checking the timing with advance on and off, well, erm.... no. Another good point, and one I'd forgotten.
However, the dizzy is only about 6 months old, a new Bosch unit bought from Burton Power.
But, i'll check it over again, with the vacuum on and off.
Cheers
