I shredded several knuckles on my 35 MK1 working
on the A4. Moyer is indeed the best source for info and support.
For electronics, in addition to the distributor,
check your plug wires too. Make sure the plugs
and points are properly gapped.
I agree that sticking valves are often the
issue. The nice thing about the flathead A4 is
that you can see the valves through the spark
plug hole. Put some Marvel Mystery Oil into each
cylinder. Then hand crank the engine while
looking at the valves in each cylinder. If one
or more are stuck you should be able to get it to move with a screw driver.
I ended up pulling the head off and working on
the valves, head and block. The water passages
in the block were my biggest issue. Crud and a
few chunks of impeller were the causes. I used
the Moyer flush kit and replaced the heat
exchanger. Never had issues after that.
Could also be a gunked up carb. If non marine
fuel was used there could be a bunch of gunk in
the float reservoir or jets. I just replaced
mine new for old. Rebuilding it also works.
The A4 it a simple machine. I'm sure you will
get it up and running just fine, in time.

Can I suggest the Moyer forum for A4 questions?
There is a lot of expertise there on A4s not restricted to A4s in C&Cs
Also I think from the sounds of it you may have
a stuck valve or 2 or 3. They will collectively
get you running again. Probably the first
question will be compression numbers for all 4 cylinders.
