I rebuilt my Honda Hobbit with a 70 kit and a brand new Mikuni 20mm carb. The moped will only run with the choke on. Once I turn the choke off it dies. I messed with the idle screw and the mixture screw a bunch and could not get it to idle w/out the choke on. I messed with those 2 screws so much that Im not sure where my baseline was anymore. My question is...where do you set these 2 screws to start? And what is the process for getting it to idle normally w/out the choke? Im a noob when it comes to carb tuning so any advice would be great.
