You set your jets for most power. Fattening them up to cover a bog will just use more fuel. Same with bigger shooters.

Before the washer trick. I was able to cure my bog with a 35 shooter but come on. I have a stock 5.9L with a vacuum carb. It shouldn't need so much shooter to cure a bog that was like yours, only under that one condition of fighting the tall gear. That's when I decided to preload the spring a bit. Ultimately I was able to go back to a smaller shooter too.

When you snap the throttle open. Can you see the spring compressing?
