what is the shipped settings on both of the air fuel screws for edelbrock carbs (1405) to be exact

mine came different

left was 2 1/2 out right was 2 out

i just want an even place to start

thanks

 

set both at your choice....then install on engine..start...then screw one side in untill rpm's start to drop...then back out 3/4 turn....then do the other side the same way...

 

I have always started at 1 1/2 out from bottom. This seems to work best for me. and then adjust from there, I don't think there is a factory setting , except maybe , at least 2 turns off the bottom.
Nice looking carb.

 

cool thanks

intake swap went great
thanks to everyone that helped
and mustangsteve.com made it incredibly easy

old out
new in
carb on
the edelbrock ford throttle adapter smacked right into the brace for my ac pump so i took the stock metal rod
got out a die and threaded the end and bolted it to the edlebrock linkage
works great
good thing my kickdown is attached to the pedal

car started right up

floats are set a little high
its surging and i can see fuel dripping from the venturis while it is idling but that should be an easy fix

 

Go to the FAQ section and there is a link for edelbrock carbs. there are videos on adjusting and troubleshooting those type of carbs.

 

start at two the get the vac gauge and go fromthere

 

do you usualy go up or down when tuning those? and adjust one a 1/4 turn, then do the other a 1/4 turn, wait for a sec, then repeat? or do one fully, then the other fully? -Jon

 

i turn one open the throttle look and listen for a change then do the next

 

found the videos

i like vids
they make life easy for those of us that always seem to miss a step with written instructions

 

Baxsom, do we bother on asking what's on that video?[8D]

Get a vacuum gauge and connect it to manifold vacuum. As long as both screws are set the same: 1.5 turns, or 2 turns, your fine. Start the motor, insure its warm, and watch the vacuum gauge as you adj each screw individually. Adj each screw, noting the turns in or out, until you have max vacuum, and don't over turn the screw, stop at max vacuum. Both screws setting should be very close the the same when done.
Works every time. I'm guessing but stock vacuum should be 16 to 20 psi, give or take.
