[C320-list] Vibration at 1000 RPMs and Perkins Injectors?

[Michael Ferguson]

I assume the prop its clean? Here in Florida the barnacles grow fast. A fouled prop can cause low rpm and smoke. Michael Nauti Clew 169

A mechanic says it may be due to a stuck injector.  Does anyone have relevant experience?
Thanks, Rollie
