I did this to try to get more power in climb. Its very good but you will always want more..... it didn't help Well 12 degrees would be a good starting point (I don't know what my pitch is I use the feeler gage thing but I don't remember what my settings are) but it really depends on how hard you want to run the engine. I find that 3200 RPM at app 60% power and 75 MPH works well for me. It is a real trial and error thing. I see 3400-3500 RPM on climb out at 60 MPH at 100%. Tie the plane down and shoot for about 3400 RPM static and you will be fairly close. Be very careful not to run at full power very long on the ground. Watch your CHTs and don't go over 375 degrees even if you have to power back a bit in the air. You can run a bit rich (to cool the engine) as long as you don't foul the plugs by going too rich. I would run on the rich side early on to protect the new engine. The valves are the weak if you get them too hot. Also I run my redrive belts loose to get things to run smooth. You will notice the engine RPM surging if you get too loose. If so power back a bit till it holds a steady RPM or you will burn the belts. I figure my engine as having 80 HP. Good luck and have fun.

I think we'll be test flying his b ird sometime this summer so this will be a great help. I still run a Powerfi n and will continue to run it when I swap engines this Spring, been using Da ve Lewis's Warp Drive protractor the last couple years and won't go back to t he pins and feeler gauges.

I did this to try to get more p ower in climb. Its very good but you will always want more..... it didn't he lp Well 12 degrees would be a good starting point (I don't know what my pit ch is I use the feeler gage thing but I don't remember what my settings are) but it really depends on how hard you want to run the engine. I find that 3 200 RPM at app 60% power and 75 MPH works well for me. It is a real trial an d error thing. I see 3400-3500 RPM on climb out at 60 MPH at 100%. Tie the p lane down and shoot for about 3400 RPM static and you will be fairly close. B e very careful not to run at full power very long on the ground. Watch your C HTs and don't go over 375 degrees even if you have to power back a bit in th e air. You can run a bit rich (to cool the engine) as long as you don't foul the plugs by going too rich. I would run on the rich side early on to prote ct the new engine. The valves are the weak if you get them too hot. Also I r un my redrive belts loose to get things to run smooth. You will notice the e ngine RPM surging if you get too loose. If so power back a bit till it holds a steady RPM or you will burn the belts.
