Steve

On run-up I get about 50 rpm change f= rom both to leading or trailing. I normally do the check at about 320= 0 rpm.

Now that you mention it, I would guess = that the occasional misfire is "probably" a total misfire of one = rotor face. Don't really know though!

Do= you ever have a similar event?
