300ex dies if choke is off

[jayhawk25]

as long as my 300ex has choke on it sits and runs fine. If i take the choke off it dies. it has a new dg exhaust and dyno jet kit. are there any adjustments to the carb I can make and where are the locations of the adjustments. It ran awsome before the exhaust and jet kit.

What jets do you have in it? Did you try the idle screw?

sounds like you are runnign way to lean. try moving up one size on you main. or if you have your airbox lid off, try putting it back on.
