Reply to "Delay Mechanical Ignition advance"

Problem solved today. None of the Springs I bought was suitable so I had to retard the initial by 4° to 10° initial and add 4° to the max advance.

10° initial.
24° advance.
34° total all in by 3500rpm.

All it did was just retarding the ignition by 4° during the entire advance schedule to avoid the pinging that occurred at approximately 2000rpm up to 2500rpm. A very annoying thing only happening in that narrow Band of RPM´s. I ran out of time today so could not try the same exercise with 12° initial and 22° advance to check if that would work. After all the more initial I can get the more crisp Idle and Throttle response. I will try one day when I have a few hours and see if it makes sense.
