Thanks for the video! I don't think I'm a fan of the way they put a blocked off jet in the carb, effectively defeating the purpose of the more expensive carb right out of the box. Hopefully the extra jet slot can be used to tune the engine to better performance than the stock 440 carb.

Very cool brother and very informative 👍

So put one of these on my 440 with a stage one, all stock internals. I put my o2 sensor on it and am finding im still running abot 11.5 afr with the stock 1.05 jet at 4500rpm and 13.7 afr at idle with a 45 pilot jet. Maybe pilot is throwing more fuel than i think, 3rd circuit is still blocked with the factory jet plug. Thoghts? Thanks

Is there a "stock appearing" carb rule at the track for you?
Just my curiousity and maybe a little off topic idk.

In the case of bracket racing at a real dragstrip no. But most small engine events and races have stock carb and carb modified classes. Kart racing for example and most mini bike drag events.
