This is an angle valve engine with 8.7:1 compression ratio.  The operator's
manual says 20 degrees but to consult the name plate.

My name plate says 25 degrees.
The plate on my IO-360C1C is marked 25 and I ran that for years as stock.  If 
you go to the 10 to 1 pistons as I did, then it needs be reduced to 20 to 
prevent detonation.  This from Klaus @ Light Speed and Lycon.
