The CAM TIMING likes to be advanced. What you did was lock the IGNITION TIMING. Totally different animal AND could be your issue.

Like RRR said and i think someone else mentioned it also, I would start by getting the initial ignition timing set lower than 36 degrees. Maybe 15-20 degree range, then see if it idles down.
