Purged the carb and it definitely helped it with the white smoke.

New problem occured today, and I'm better off compiling my issues on my build thread rather making new threads for every possible problem. So I was on the freeway, and I heard a weird crackle sound. So I decided to accelerate and switch lanes, however no acceleration. So as I was in the shoulder lane, I'm trying to figure out what happened. Turned the engine off then on, and tried accelerating, still nothing. It does go into gear, but no acceleration. Im guessing it's the slave or master cylinder? Any inputs?
