Engine warm. The bog feels almost the same as when it's not warmed up but not as bad. I have good throttle after the flat spot. Timing, dwell, idle all good. When I pull the choke about half closed it doesn't bog. The carb has been rebuilt and the accelerator pump if fine. I didn't know if there was a circuit for off idle that might be clogged. I guess I need to take the carb off again to see if a circuit is clogged up.
