Weber 45 DCOE too small?

I have bought one l bologna Weber 45 DCOE. I pulled out the Emulsion tubes and the idle jets. I don’t know the exact name for all the parts however from the top down on the tube. Correct my terminology if you can.

160 air corrector

F15 Emulsion tube

150 Fuel Jet

And 60 F2 for my idle jet

While you’re at it does anyone know the correct fuel pressure I should be running?

Thanks a lot for sharing some of your knowledge.

Will this be for a street port, stock, 12A or 13b.

12A Street Port 45DCOE with below setup pushing 137 rwhp & 229 tork

Idle Jets=60F9
Main Jets=200
Emulsion Tube=F11
Air Corrector=170
Pump Jet=50
Chokes=40
Auxilliary=4.5
Fuel presure no higher than 3psi more like between 1.5 to 2.5 psi
Needs high flow not high pressure

What about a stock port 12A? Any idea on E tube sizes or if these would cause too many problems for me?

Stock 12A I used:

fuel presure 2.5 and not less than 1.5 at full throtle

Idle Jets 60F9
Main 165
chokes 36
Auxiliary 4.5
Pump Jet 45
Air corrector 160

Try those setting, you might have to go either up or down on the mains and air corrector
