Ok, seeking advice. I have that transition hesitation that is our common Weber battle & want to spend as little money as possible to get it right. Price of these Damn parts will keep a guy hungry.

I've gone up with the main jets & gone up with the idle jets & neither has solved it. I double checked the float level & fuel pressure @ 3psi. I've read through this thread again & as I see it I have two options #1 go down with the idle jet holders to 100 or #2 change emulsion tubes F11, F16???. What does everyone think? I'm leaning toward the jet holders but thought I'd tickle the minds of a few of you...
My setup on a 289 (294CI) is:
48IDA WEBERS
Choke 37mm
Idle fuel jet 65
Idle jet holder 120
Main fuel jet 150
Air Corrector 120
Emulsion Tube F7
Accel. Jet 50
Screws set at 3/4 turn
