Carby dellorto sha… need help tuning

[jbburns99]

just picked up a new dellorto sha carb (it is a clone). got it on the bike and running. no power, won't idle.
removed air filter and she runs great though still no idle. soo need a smaller jet i'm guessing? I was wondering what the size
of the stock jet is, and what size to change to. i live at high altitude (roughly 7000 ft). I was also wondering
if this carb has a simpler way to increase airflow, such as the slide needle that comes with the stock carb.
This thing is pretty foreign to me and I'm not really wanting to pull it apart until i get a little bit of background from you
experts. any help is appreciated!
Also already orders some 50s jets

that carb has a main jet as the only changeable jet.
other than that it requires southern engineering.
