AFter the cam shaft timing change the motor was ALOT better but not well enough for me to risk the new p-47 but I am going to remove the motor from the fus and bench run it for a while until it learns to behave... I do find it odd that the cam had to be retarded to run right...... Makes me wonder if the cam is marked wrong or possiably the wrong camshaft all together.. but... We will see how it goes. As far as brands go: I know Satio is a killer motor but I have nothing but good things to say about the Magnum motors.. all the ones I have had any contact with have been good reliable engines..Maybe not the most powerful engine but worth the money for sure.. I have 5+ Gallons of fuel through my 52-4 stroke over 6 years with just valve adjustments...I like mine alot!
I have the 120 in the stearman.. a good match for me...Thanks for the intrest.. I will follow up with a report later on as It goes...Have a good day flying!
