I was castigated for my comments regards the following post on another Forum. The report is from the Northern hemisphere and they are just coming out of winter.

I would be keen to hear on the thoughts of others in this part of the world.


Went flying after a few months off on Friday. While the battery was plenty good
to spin the engine over, it took a few tries to start my trusty fling steed.
Seemed to start and then die again quickly only to start again after repriming
and repeat, Finally caught and after a little lumpy running, came to life as
the stellar performer I am used to. There is less than 300 hours on it since
rebuild. Preflight, runup, and takeoff were uneventful and I and my new to
flying friends were into the blue.

About ten minutes into the flight I noted that on power changes I was beginning
to detect a miss that got worse when the throttle was retarded and better when
firewalled, and that I was not at full power at any stage.

Messed around with leaning for a few more minutes hoping it would sort itself
out and then, since we were over water (Puget Sound) thought discretion was the
better part of valor and informed my passengers we were having a bit of an
issue and needed to call it a day.

Got ahold of the tower on the by now other side of the sound and informed them
of my problem and that I would be coming in high to assure I could cross the
sound. Once across I had to slip pretty hard to make the runway and of course
they had to make me feel foolish by have all the fire trucks, etc out with
lights blazing.

Motored back to the hangar on my own power still aware of the significant
missing/sputtering and just parked it for the day.

Now I am curious as to the cause, be it fouled plug(s), bad mag, gunky carb
whatever.

Anyone have a similar experience and care to make a guess? 1968 variety
Cherokee.....?
