I spent a weekend at Cutty two weekends ago.  It was blowing hard enough out
of east to make outside moorings/anchorage uncomfortable for all by large
cruising yachts.  In a frontal passage conditions, winds blow E and NE and
Cuttyhunk is fully exposed and miserable.  

There is a sandbar however to the NE with a small colony of seals on it.
Nobody goes as the bottom is kelp and thought to not hold well.  Very nice
and Calm in those conditions  I have done it on 3 occasions over the last 2
years and got a good night sleep watching other anchored boats rock and roll
across the harbor.   And my kid loves watching the seals.    

  

In terms of A4 I would suggest

Spare clean carb ready to go is priceless.  On numerous occasions I swapped
carbs while under sail.  You can then clean the crappy one and use it as a
spare.  Your problems sounds more electrical then fuel. 

Get electronic ignition, and an appropriate coil.  You can find them around
100$ or so.  

Make sure wires and sparkplugs are good quality.  

Distributor cap and rotor should have nice clean contacts. 

Have few spare coils.  

How is your oil pressure?

Alright, the saga continues.

We went for a sea trial Sunday after the changes, i.e. Vent line cleared,
filters changed, clamps tightened.  The engine ran great all the way to
Cuttyhunk. I probably ran it about 3 hours. Two of those hours I ran it a
little harder than I normally do after having read Don M's reasons for
having black sooty spark plugs. I thought my problems were solved.

On our way home from cuttyhunk, We motored out the harbor and decided that,
because the wind was a little light, we would motor home to run the engine
some more. 50 minutes into our ride home, the same thing, only a bit slower.
the whole, slow, stall happened over maybe a minute or two. Some sputter,
then run normal, a little more sputter, then normal and then a slow stall.

We then sailed home and into the mooring field. This is actually a benefit
of the engine troubles, I've been a bit intimidated about sailing onto the
mouth of the river due to the current and very tight channel flanked by
shoals and some pretty ominous looking rocks. I've now had to sail into the
harbor twice over this last weekend. At one point we were probably doing 4
or 4.5knts through the water but only 1 to 1.5knts over the ground fighting
that current. On one side of the boat it a big, rocky cliff and the other
shoal. it was a little adrenalin pumping! Anyway, the approach to our
mooring was dead, head to wind, along with the current in the same
direction, I lost forward motion under sail and started the engine. She
started right up and we motored onto the mooring without incident.

So, safely moored, I pulled the vent tube, it was clear. I then went below
and pulled a spark plug and it was all black and sooty again after maybe 4
hours running time.

I used the Moyer rebuild kit on the carb that is on there now. I'm not sure
but, I think I changed the main jet to the moyer recomended one at that
time. I think it came with the rebuild kit.

My earlier idling issues seemed to have been solved by swapping out the carb
that came with the exchange engine for the one I rebuilt off the original
engine and had just sitting around as a spare. I think what I would like to
do now is, clean up the carb that came with the exchange engine. and swap
them back out. I'll then replace the plugs and run it some more. Unless you
guys think I should maybe try another path forward.

P.S.  Cuttyhunk was Amazing!
