The carb is marked Sheng Wey PZ20.

I was gonna start by bumping up the idle, it was too low. But today it doesn't want to start at all. I knew I was buying a stack of parts. Now I get to do the set up!

Luckily I was only doing short warm up trips around my neighborhood when mine was cutting out. The other odd thing is the 2020 speedo seems to be non adjustable for the wheel diameter to adjust the mph to a gps. I put a 2019 speedo on and dialed in the speedo to gps accuracy. They (China) could improve so much by just doing a little bit of QC before sending units out the door so quickly.
