Plug leads in right place? Timing gun on right lead? Double check. 30 degrees just to get it to run is extreme.....

To be honest I wouldn't have thought you could get an engine to run at 30 degrees advance. If you were able actually start it I should think it would kick bacl, run very hard and pink like buggery. I would be interested to know about you timing equipment and your procedure.
