[TR] Another Crazy Question: Beware, chestnut related

[terryrs at comcast.net (terryrs at comcast.net)]

Haven't researched archives, so don't feel obligated to respond.  I seem to 
remember hearing a couple of different recommendations on how much to set the 
advance on a TR3A engine.  ISTR one was 4 degrees, another lister thought 8 
degrees.  Engine is at I think 4 right now, but running as if it lacks the pep 
I'm used to.  

Thoughts?
