carb and intake

Yes, change out the thermostat first to eliminate that as a cause. I would also advise you to run a simple check for any vacuum leaks around the manifold and carb with a can of carb cleaner. Just to eliminate a vacuum leak as a possible cause. Then I would look more deeply into the adjustments on the carb, specifically the secondaries. It may be dumping way too much fuel initially causing a hiccup before the engine can catch up with the fuel flow. A recurve kit on your advance will probably help as well. Just a thought, with a stock convertor you may not be building enough RPM's directly off idle acceleration to allow a complete burn of the fuel entering the chambers. Good luck
