I got the engine running today. The wooden propeller from the 532 wouldn't fit, so I started off with my new 68" Kiev three blade propeller. The instructions said that the starting point for a 582 should be 11-14, so I set it at 12. The old 532 Tachometer seems wildly off, so I have connected up a Tiny Tach. I warmed up the water temperature, increased throttle to get the EGTs up and then pushed it up to wide open throttle, but only got to 3400 RPM. I am running a 2.58 gear box. I am not sure if it is the throttle assembly or the propeller that is giving me the issue. So can anyone provide at least some idea of what pitch should be used? I tried the test twice and still need to break in the engine. I am currently running the gas at 100:1 in addition to the oil pump as recommended by Rotax in the 582 installation manual.
