Ok, On my wifes 1999 Z370. I take off and after about 45 seconds it starts to bog like its starving for gas. I have to flip the choke half way then it will wind back up for sec then want to stall. When I have it idleing it will drop a cylinder and only run on one. I give it gas and it will run better for a second. I took the carb apart and cleaned it up good and still same problem. I hope somebody here can shed a little light on the situation. Thanks!!
