Finally got it run. I had the heatsink header remove and other under the heatsink header to pour out the flooded.

After i got it start for break-in, When it start. the wheel start climb up the speed and i couldn't let it lay down on the ground because it will run away. Is it suppose to be like this when break-in? Should i adjust the idler or what?

Also, There was some little fuel spitting out the exhaust, I also pick up the chassis and try to pour out some fuel out of exhaust, there was some goo goo fuel coming out in brown and blackish color. Is this normal?
