<VV> Stumbling acceleration

[J R Read_HML]

Well,

If/when you solve it, I'd like to hear the solution.  I've been dealing with 
it (and have partially improved it) for a while now.  I THINK it may be 
related to carb jetting and/or accelerator pumps.  I have already changed 
the springs and weights in the distributor so that the advance comes in 
earlier and that got rid of about half of the problem, but not all.  I'm 
thinking about possibly adding the accelerator pumps to the secondaries 
since the problem is right at about the point where the secondaries would be 
starting to open.

But, I have an unheated garage and it is COLD out.  So, I just might wait 
till Spring to see if it fixes itself.  <Big Grin>

I did recently purchase (not yet installed) a set of Seth's plug wires. 
Perhaps the solution is waiting on my TO DO shelf right now?

Hi guys-
I'm hunting down a stumble in the acceleration on my '65 140.
When I'm accelerating I get a miss at about third throttle.
I've checked to make sure all the cylinders are firing. The Carbs seem to be 
working, but I could be wrong. Both function well. The accelerator pumps on 
each carb works. They seem to be drawing the same amount of air. I have 
Bosch platinum plugs with the four short terminals around the center 
electrode on the spark plugs. So no over the top terminal on them. If I'm 
light on the pedal, I can get it to smooth out as I go beyond the 1/3 
throttle, but it is still somehwat rough.
Anyone got an idea which things I should check first? Should I be looking at 
a points problem?
