86 t/a lg4 running rough
Ok when I start my car (been sitting on and off for about 2 years) It stubles all over the place if i let my foot off the gas it will stumble and die. When you rev it up it chokes and i can here **** shooting from the carb. Until it warms up but even then it wont hold idle unless I adjust the idle to about 1100rpm. Any ideas? i just swapped this carb in from a 87 LG4 car. My previous carb would idle smooth in gear but would stall when put into any gear.

Probably need to adjust the carb to the motor. For ccc-qjet adjustment procedures see:

Make sure when it's warmed up that the choke blades are fully open at 90 degrees. Plug all vaccuum lines at the carb while diagnosing to rule out vaccuum leaks.
