dang that Murphy

Just when I thought we had the Skyhawk ready to blast off next week for Florida.....we took a little ride Saturday and on the way
back she ran rough for milliseconds on two occasions. The 1st time was so fast, Donna didn't even notice. The second time she was
expecting it.

Any ideas?

The cylinders were gone through about 200 hrs ago.

In-flight mag check was fine. The mags are newish and maintained.

Leaned according to the POH.

We did seem to be picking up a bit of carb ice. (and by the way, how rough is rough when the ice melts)

Should I worry? Maybe do a MMO injection and a special dance? Plan to drive to Florida because the wx will be crap anyway?
