I having a problem with my holly carb not sure what series it is. but the other day it started running funny out of no where. tried to adjust the fuel air screws, it runs fine for a while but starts running funny again after a couple miles. I've re timed the motor and every thing, iv got it running ok right now but it is horrible on gas now.. any suggestions??

Welcome
Check for air leaks, carb, carb gasket, intake, inspect each vacum line for a dry rott break & that there not unplugged. Do you have a good fuel filter on? If not you may be getting trash in carb.
