I had an old tired one and put a set of Millineum cylinders on. Then next annual I had the timing put from the retarded 24 deg. to the allowed 28 deg.<br />
This really made the difference<br />
Later Sensenich came up with a new twist profile for their metal prop on the C150, which gave another improvement.<br />
If you can get a large wood prop and 28 deg. timing, I think stock compression ratio for an O-200 would be enough. There might be someting to be had with better exhaust.<br />

Carl before you spend any money have your crankshaft checked for cracks and dimensions. A lot of higher time 0200 engines have cracks. Lee

<p>not sure but I think you could use the piston and cylinders used in O-200D (higher compression) although in my new O-200D timing is still 24 degrees TDC. the balanced set makes for smoother operation</p>
