adjustment screws (3)
« on: March 17, 2019, 10:47:44 AM »
ok laugh at will....So my paper full of notes on the carb were used to start a backyard fire pit last night by my 8 year old.

so here are my questions:

1. how to set the idle mixture screws for initial setup?

2. how to set the  APT screw  for initial setup?

I'd start 3-4 turns out & 3-4 turns from bottom on the APT.
