Yes. The float level can be adjusted. Usually by bending the 'tang' that the needle(of the needle and seat assembly) is attached to on the float assembly. A general rule is to start with the float arm 'level'the bowl has fuel and the vacume likes are connected.it is a new carb it has all new fuel lines and the small fuel pump seems to be pumping. can you adjust the level of fuel in the bowl??
Work with what you have. Go back and retrace your steps.its has a elcetronic choke. i cant tell ifit is working. i disconected it, but it still does the same thing. i will look at the carb tonight to see if that is what causing the problem. but on a nother note, i have two new carbs and when i swap the out, it still does the same thing. let me know what you think.
