This is in reference to my parallel valve IO-360:
The concensus seems to be that standard advance curves on the Surefly are too aggressive, with max timing up to 38 degrees. This increases CHTs with no benefit. It seems like it would be simple to set the engine to 0 degrees TDC, then turn the flywheel forward 5 degrees before setting the final mag position. Using the 25 degree variable advance setting on the dip switch, I would get base timing of 20 degrees, and max timing of 33. This seems less aggressive while still giving the advantages of advancing at lower MAP. Thoughts?
