Is this possible?

[Donzi GT250]

Alignment checked with alignment rod all looks good.
But if I turn engine over looking at the coupler it seems the coupler has a slight wobble(slightly off center)
Have been running this way all season with no noticeable vibrations.
Is a slight amount of runout of the coupler acceptable?

looks can be deceiving. no vibrations no problem...IMO

If it has any measurable runout, then the alignment bar will not slide in when the engine is rotated to different positions.
if the engine is shaking on the mounts at idle, could be a bad mount....I suppose that might look like a runout issue, but go by the alignment bar.
