As some of you know, I recently swapped in a Z400 carb, it was perfect for a while, but it seemed like it needed rejetting. I put in a 145, then went back to a 147.5 main and now it will barely go past idle. With the choke on, it'll go to about half throttle, then sputter and miss as if it's not getting enough gas. With the choke off it won't go past 1/4 throttle before it does this. The float height is fine now, it was way off before I adjusted it. I can't seem to figure out what the hell is wrong. I blew out all the jets and the places they thread into with an air compressor, that helped a bit,but it still sputters. It idles perfectly except when the revs come down, then it idles lower for a bit and returns to normal.
