Anyone have any experience or knowledge about these adjust-a-jet kits? (are they junk?) http://www.summitracing.com/parts/PHP-15001/ And whether they make one or are compatible with Demon Carbs? I've done a little looking around but have not found anything out. I think the design of the float bowls on the Demons might be an issue with these things.??o No:
They are one of those things that look really good...but I don't know anyone that uses or knows much about them. And they have been around for a while. Too good to be true??o No:
