I'm not necessarily saying you need more than 34 degrees. What I AM saying is the timing marks- if not verified- might be making you think you have 34 degrees when you may not have that much.
The timing marks/TDC should be verified. A quick test for a lack of advance is to do as I said above- crank in some more timing to see if the situation improves. If it does, this might be pointing to an erroneous timing tab/damper line, or a problem w/the cam timing.
