You are right of course - all I was warning was that if you follow the 
manual settings for advance on the distributor (which in my operations 
manual says that for a new/rebuilt engine the advance vernier should 
have the long line aligned with the arrow)  this may not be the optimum 
setting given the difference in fuel types.
