The V-stack is an engine part, you will need to call if you want to order engine parts. The V-stack will not help the condition you describe, first thing I would do is get some regular gas, 87 octane and don't worry about the 10% alcohol, will run for years without a problem.
Start over over with the carb adjustments, go here;

jedijody,
It has been a wile since this was posted, but I thought I would get back to what I did.
I set the gallon of fuel I had left that was mixed with non oxygenated fuel, and mixed up 2 gallons of fuel using regular gasoline. I fueled up with the regular gas oil mix and readjusted the carb again. The engine ran better with the regular gas oil mix right away. I think the engine still needed some more break in time, because the carburetor still needed some adjusting during the next two gallons. The engine really came in on the 6th gallon of fuel. It was running extremely strong and not as much vibration.
I still had the gallon of non oxygenated gas oil mix, so I figured now that the engine was running well, I would try this mix out again. The engine was right back to rough running, kind of a missing sound, and seemed to load up some. I tried to adjust this out with the needle, but it couldn't be smoothed out. I burned up about 1/2 gallon of that stuff that day and the engine never did run well. I went back the the regular gas oil mix and all was well again.
I guess my engine just doesn't like the extra octane of the non oxygenated fuel. I take it that it was the extra octane that caused the problem?

Woo-Hoo! I got something right!
