Ok, so I got this crf 50bottom end, with the new tb race head 88 kit on it. It came witha sheng wey 20 mm carb.. Ok, installed the carb, when I give it throttle why does gas shoot out the back side of the carb. If I dont have the air cleaner on, it will shoot fuel out of the hole... My slide also only goes down as far as illustrated in the pictures...... Help me. What do I need to do to get this thing set up right?
