Check the throttle cable and housing first.Pull the fuel line from the carb and crank the engine over. If you have a steady pulse of fuel,you can eliminate the fuel pump and inline filter.Plus pour some of the fuel from the line in a clear container and see if you have water in the fuel. It will settle at the bottom.Just cleaning a carb may not always help also. If you didn't install a new carb kit or at least a new needle and seat you could still have carb problems.Adjusting the float level is something a lot of people never check also. Here's the same basic BST40 carb on a Ktm. Look towards the bottom of the article on carb assembly and adjusting float level. The BST-40 Bible - ADVrider
