Rough Idle Once Engine Warmed Up

639 Views 1 Reply 2 Participants Last post by  Travis98146
Hello folks I've got a 64 1/2 with a 260 v8, 2100 2bl carb. Engine starts with no hesitation and runs super smooth when cold, even after sitting up in the garage for several weeks. But recently once the engine gets warmed up after riding around for a while it starts to idle really rough when I stop and has almost stalled a few times. Any thoughts on what to check on first? Vacuum leak? Clog in the carb someplace? I changed the plugs and coil a few months back, but didn't change the plug wires or anything on the distributor. Having trouble deciding where to start since it only happens when the engine is warmed up. Thanks in advance.
