Stumble issue

69dart440 said

Have not checked float level.
Dont know vacuum.
Silver spring in now. (heaviest)
I think the metering rods were 6842. Which seems very rich to me.
Its in top hole on pump arm.
Electric choke. Choke seems to work great.

I know I have to to my homework and check float level and vacuum. I just dont have a vacuum gage right now. What should float level be at? Also should probably look at jets when I have the top off.
Again thanks for the help!

Ok....
Heres the set-up you need to follow. You have your carb set-up completely wrong.Cant keep going back and fourth if your not going to listen.Dont take this the wrong way,just trying to help.The reason you have a stumble off the line is because of your pump shot. Wrong hole,farthest out is the least amount of fuel.The car is falling on its face because it has the heaviest spring in it,thus not opening the metering rods fast enough,if at all in the power mode.
THE CAR IS STARVING FOR FUEL !

:Bring this carb back to stock calibration: 1411 Edelbrock
Main Jet-1432 (.110")
Secondary Jet-1431 (.107")
Metering Rod 1459 (.075"-.047")
Center Hole Pump arm.
7/16" Float level
"ORANGE" Spring
A/F screws out 1.5 turns
Make sure the choke COMPLETELY opens when hot.

Do this and then tell me what its doing.

By the way,have you checked for any vacuum leaks ?
