Thanks all. Fuel should be fine. Cutlass bearing seemed ok, when I checked.

Cutlass bearing wore?

You may want to check your fuel delivery circuit, since from the description it sounds like something's momentarily interrupting the flow. Could be filters, could be an air bubble, could be something else entirely.

Just a thought...

Azzarac Did you only begin to notice the vibration after changing the prop? Do you still have the old one? You may want to try swapping them back and see if that alleviates the problem. It's odd to occur thru the whole range of rpm.

New prop - periodic engine vibrations

we've got a new prop (3-blade, fixed) and we have observed that the engine trembles slightly cca every 5 seconds. The vibration is very light and it's constant across all rpms. What might be the reason? Too small pitch? This propeller should be a copy of our old one, but probably not a 100%.
Many thanks for any insights!
