<VV> 140 fine tuning questions

[N. Joseph Potts]

With the engine off, move the carburetor linkage by hand and confirm that
you get a squirt of fuel into EACH carburetor (I'm assuming they are 1966)
when you "floor" it. You may have a failing accelerator pump. After you've
depressed the pedal once before starting, take your foot OFF the pedal
before cranking. That's what the Owner's Manual says to do, and it works
better.
     My favorite ignition system is stock points (coil, wires, plugs, etc.).
I've tried others.

I have a recently rebuilt 140 that has about 1000 miles of break-in so far.
It's running strong and I'm pleased but there are 2 issues I think are
related that I want to fix.  First of all, when I don't drive the car for a
day or two, it's hard to start and requires several pumps on the gas to get
it running.  This wasn't the case right after the rebuild as it would fire
right up on the first crank with only a few turns of the starter and only
setting the choke with the gas pedal then holding the pedal half way.
Secondly, it was running real smooth under all conditions but now, when I
accelerate hard, there is a hesitation followed by what sounds like a little
backfire, then it takes off.  I have a powerglide transmission and when I
stomp on the gas this hesitation also affects or delays the downshift into
low gear.

Seems to me like it's a carburator issue but I'm not much of a mechanic.
With 4 carbs running relatively well (other than this problem) I don't want
to screw them up or make it worse.

Even if this is a carb problem I'm contemplating replacing the new points
with an electronic ignition set up.  Which electronic ignition systems do
you all prefer?  I want an affordable and easy to install set-up.
