Having some trouble with my pinto powerplant this weekend. About halfway through a session when everything gets good and hot the engine starts faltering/hesitating like it's misfiring. I am pretty sure it's not a fuel/carb issue, filters are clear and the bowl is full. I also tried lifting on the throttle then stomping again to see if it was an empty bowl that would fill to rule it out. I've replaced the ignition module and the coil with new ones but the issue persists. Going to replace the distributor cap, wires, and plugs next but that all looks pretty ok to my untrained eye. Anyone got any other ideas?
