when you buy something they should WORK,Period! one of them will not take Fuel,so i am gonna play with them to see if i can get them to work? try adjusting Float then i guess move on from there. again only should have bolted up and run other than Jetting for my Area. PJ's are some good carbs and they are going on a small bore motor i ride the Dunes with, but i run Lectron;s on my Draggers! This Guy could be a cool guy but i cannot get ahold to him to work it out?
