Engine Dieseling - Options?

its automatic, plugs were ehh, car was pretty rich with the carb straight out of the box, a step I generally do with new carbs is take them apart to check for cleanliness and what guts it has - I skipped that step this time around due to wanting to get the car started initially, I pulled and cleaned them after cam break in but didn't look at them again until the new ones went in, the new cold plugs are clean as can be after two 30 minute run times, I can get a pict of the plugs later this week
