Ok apparently I didn't try to start the kart enough times or I
flooded it and it started fine the other day. Cool. So I let it idle
at about 1500-2000 RPM I'd guess for about 10 min.

What do i need to do now to break it in properly?

I got an autocross in about 2 weeks so I got some time to get it done,
but I want it done right. Coming from stock class cars to this I have
no clue what I'm doing. :)

Thanks again guys, I appreciate all the help.
