MySaito is not strong. Does the timing being off a little effect the rpms? Engine runs fine but only gives about 9100 rpm with a 13 X 8 apc prop... The engine received new bearnings and seem to be find until I put it in a Extra 540, 60 size airplane.... I have checked everything and can find no air leaks and the low end and high end adjustments have been checked and rechecked my many other experienced pilots... How would the timing effect the engine if it were off one tooth?
