Is the float level set up right? All the seals are good, including the one on the choke, choke tube in the right place? I would inspect it visually very VERY closely and compare it with genuine oem ones you took off,also check the slides are in the right carb. YOU have to pay attention to the smallest detail, get the calliper out and carefully measure everything because with those cheep nasty knock off's you might get pair of good ones or trash. You never know. Sent from my VOG-L29 using Tapatalk
