[truckdude239]

when ever i slow down (an stop light) i push th clucth in and when the motor idiles down it will stall its fine if i rolling down the road runs good but when i stop or sitting still its runs rough and stops. i don't know where the choke is only thing i see an metal pipe running down to the exhast manfoiled the pipe comes off the side of the carb i tried to adjust the linkage but its adjusted all the way out i have the stock 2 barrel carb any ideas thanks in advance
