When flight-testing my RV4 (O 320, wood prop), this happened: All went fine, but when applying full throttle after 30 minutes of flight the whole aircraft started shaking (amplitude app. 5 times per second) so the gauges where shaking and the canopy shakes as well. reducing power just a litlle bit and the problem disappeared. The follwing was tested to avoid this: Running on 1, 2 or both mags, giving electric fuel pump as well, pulling carb heat, turning the prop by 180 degrees. No success. It happens with full throttle, no matter what RPM, but only from time to time. The aircraft is equipped with an Ellison TBI.
Any idea what could be the reason??
