I have a BME 102 that turns a 26x10NX 6000rpm.
I installed a 3W intake manifold and the rpm went down to 5750rpm.
I noticed in the air the propeller was louder. I can only assume that I am not getting any blow by in the intake and all the fuel is going into the engine. I think I need to lean it a little or it was too lean before. It didn't run hot and never had a problem! Engine is still tight compared to a couple of others that I have flipped. Does this mean that it is not broken all the way in yet?
