Can anyone provide me with tuning specs for my '68 Z/28. Timing, dwell, idle speed etc. Thanks

Dwell is 30 degrees and timing is 4 BTDC and idle speed is 900 (between 950 and 1000 RPM is usual).

Thanks, I had the carb rebuilt by Jerry McNeish but it doesn't want to idle. It acts like it loads up and falls off.
