RE: tuned pipes
I'm listening to ya! Just took out 3, 9 inch props and will try it. I have not run the engine due to weather conditions (it snowed this moringing[:'(]).
My thoughts were to try the 10 x 6 APC, then try some 9x5, 9x7, 9x7.5 and 9x8 APC's I had laying around. It just seems to me that a 9inch prop on a .46 engine will get PRM, but will the engine last?
I did have to richen up the lowspeed needle to get the idle and transisiton the last time I ran the engine with a 10 x 6 prop.
