For you 914 drivers;=0A=0AMy 914 started showing surges in the manifold pre
ssure recently.-On takeoff's, the MP would vary from 33" MP to 39"MP. In
cruse mode where I normall cruise at 33" MP and 5300 RPM-I was having to
advance the throttle, or retard, in order to keep the MP stable.=0A=0AThe e
ngine has 860 hours, TT since new...to make a long story short, I have adde
d 3 pictures of the servo cable..Over a period of time, some of the wires i
n the cable, were broken, or just worn out.-The -clevis on the end of t
he cable connects directly to the turbo wastgate, and the worn out cable wa
s just bending, instead of moving the wastegate...=0A-=0AI ordered new ca
ble from Rotax, and installed...Make sure when installing new cable, that t
he wastgate is completely closed..If its not completely closed, you will no
t get full bost on takeoff.=0A=0AJim Brown
