these guys are great. i ordered a carb for the chevy pick up and when it got here i put it on and it did not work right would not idle or anything. after several attempts to get the carb set right, i called carbs unlimited back and spoke with a csr named bob. told him my prob and that i wanted to swap out for a new carb of the same price. i sent the old on back and the new one was sent out today. good bunch up in washington :thumbup :thumbup
