Air Fuel Ratio while on the stop?

[Mike Hedger]

I also have run both and hands down I would run an air baseplate #1 stop to control ET and a K&R inline for a starting line control I have had great luck with the two of them. However if you run alcohol you need to cut the blades on the engine side of the throttle shafts so it won't puddle fuel on the blade then go rich when you go back wide open. I also am not a fan of electric stops on high HP cars they open up to quick and you take a chance of spinning the tires when going back to WOT. If you want to spend the money and get the best out there go to the #1 three stage stop you can use the bottom cyl. as an override a high gear or bring the top off and then the bottom to get down a bad racetrack. I ran a S/St car that ran 10.90 @ 145 and could get down any track I went to with this type of stop. But back to your question if the carb is correct in the air bleads and intermediate circuit the mixture does not change mutch when on the stop but this takes a good carb guy and about 10-12 passes the same day to get it correct. (at least this has been my experience)
