MEP-806B Engine will not shut down

[Robertmason89]

Howdy all,

Lucked up and acquired a nice 806B. Didn't need much TLC to get it running. The usual change the fluids, filter and fresh batteries. Cranked and started right up after priming. Let it run for a few minutes checking for leaks and so on. Attempted to shut the engine down by turning the Engine Control knob to the "off" position. The engine just idled down real low, even after turning off the master switch and panel light the engine continue to low idle. I got it to shut down by starving it of fuel. I've checked the TMs with not luck. Has anyone had this issue before or have any suggestions.

Thanks,

Mason

Did you have to manually prime and or bleed the system?

Sounds like an governor actuator issue

read and test the throttle controller with this manual.
