David,
If at all possible you should put on one of the aluminum pulleys with the degrees. On my Puma,to run the best I have the timing set at 10 degrees statically (with the test light) When the engine is running, the timing maxes out at 30 degrees when checked with my Craftsman timing light.
Best regards,
Jim
PS
Just took the pedal cluster out of my Puma to send it to Pedal Werks in California for a rebuild. New shift bushing is next.
