1407 elderbrock carb questions

[drivers mopars]

just tried a 1407 750 cfm carb used on my 440

bot from guy at track with jet kit rods

looks hardly used but may of sat for a while

i opened it up put rods and jets in it that may work on my 69 440 with 474 cam 9.7 comp.

i did have a stock avs on it, tried to fire it up
acted like it was not getting enough fuel,
i left choke open, it tried to start but never did
took it back off,turned carb over and lots of fuel poured out. put stock avs back on, fired right up. Whats wrong with the 1407?
also will the linkage kit thy sell fit my 69 c body????? i put the throdle rod off my avs on the
1407 but hit the rod for the choke when floored
. do i need to rebuild the 1407. is something bad?

1) did you pump the throttle and check for fuel squirting out?
2) did you check for an overly rich or lean condition?
3) check the idle mix screws at the bottom front of the carb. Turn 'em in SOFTLY and back them out 1-1/2 turns to get a starting point.
4) did the throttle plates move with the throttle?


There's lotsa stuff to look at. I have no idea what you tried. can you give us a little more info?

Two things you should check. Take the cover on the top(bowls), and thouroughly clean, especially the needle and seat assy. Mine stuck open after sitting only 4 months, but at that time I had a rusty gas tank. Second, be sure not to run more than 6psi to the carb, 4.5 to 5 would be much safer, they just can't take the additional pressure and you'll have fuel all over! Post again if problems persist. <><

The linkage should not be a problem, just use the Edelbrock adapter. I have a 1406 on my 65 Fury and it works perfectly.

JUST A THOUGHT.I HAD A SIMILAR PROBLEM,THE FLOAT DROP WAS WAY OFF,NOT ENOUGH DROP.NOT LETTING FUEL IN FAST ENOUGH.........GOOD LUCK.

i forgot what the measurement is and how to measure it on my 1407?
ill think i need to check that 1st
and ill clean needle and take it apart alittle more,

AS I RECALL IT WAS 15/16,MEASURED FROM THE TOP OF THE VERY END OF THE FLOAT, WITH THE GASKET ON.ALSO LOOK AT YOUR FLOATS AND MAKE SURE THEY ARE STRAIGHT & NOT HITTING THE SIDES OF THE FLOAT CHAMBER....LOOKS LIKE THE C..BODIES ARE GETTING MORE POPULAR.I HAVE A 63 NEW YORKER.HOPE THIS HELPS.
