Adjusted float height to a little more than 1/4 inch down. Runs but stutters out if you give it gas. I am surprised how low this is going. The adjustment sheet calls for 1/4. Ill adjust it some more and see how its doing.

edit..

Idle adjustment is 1.5 turns out. What should I look for as far as vacuum goes? I just bought a vacuum gauge the other day so I can check.

I took this carb off 4 or 5 times again adjusting from 1/4 inch down to now 9/16 (i think this is way too low but I have no experience). Each time it would let me give it a little bit more gas before sputtering out. Even now it is still no where near drivable. Whats goin on?
