I just sent my carb in to Daytona Parts to get a proper overhaul. Tim and AJ from DP were very help and knowledgeable about the 1920. I got tired of waiting for friends that said they would help and I paid a local guy 50 bucks plus 35 for a NOS rebuild kit and it still did not work well. Wish I knew more about this stuff but I just want to drive. Hopefully, it will be back this week.
