it will idle great when you go to give it any gas it cuts right out, it will rev to the moon and sound and ride great with the choke on. its not a blocked pilot or anything like that ive gone through the carb very well. its not an air leak also, i can adj the fuel mix screw out any and it doesnt help or make it worse, i can also adj the needle clip position all the way down so rich as it can get and it still doesnt do anything. if its running better with the choke so me its very lean yet the needle position doeswnst effect it one bit, any help? thanks!
