close up of driver's side AVS OEM carbs on engines...

[hemi68charger]

I need close ups of your OEM set up AVS '68-'70 carbs on your 440.. I'm trying to get this accelerator pump problem straightened out. It seems the pump isn't making a full cycle of movement to both discharge fuel out the discharge nozzles and then coming back up to suck fuel to replenish the pump reservoir...

Thanks..

Here is a shot of a 1970 Carter AVS.  Can't recall the number.

Mine's a '70 with A/C. Notice the idle solenoid. Sorry, pass side is all I could muster at this time.

Sorry about the blurriness.  Forgot to set the macro on the camera.

The car is a U code 4-speed manual brake non A/C car

Thanks guys,,
I see most have their accelerator pump activation rod in the middle (b) hole of the activation arm. That's where I have mine as well...  The problem is when I give it a complete full-throttle activation on the pedal, the pump isn't moving enough and I'm not getting a discharge of fuel out the nozzles for initial start-up. I've had the carb off the car, on the bench and have manually pushed the pump up and down and I do get the appropriate discharge. Apparently my linakge isn't allowing the pump to go down far enough and then back up enough to replenish the reservoir for the next squirt... Grrrrrrr  I may have to bend the accelerator pump activation rod per the service manual...

My carb setup is just like all of yours..  OEM original carb for the '69 440 HP 4-speed..........

Move it to the outer hole, that should do the trick.

I did that and it didn't seem to help.... Maybe the leather on the pump piston still needs to expand some... I'll check out the situation today when I get home and with a cold motor to see if I get a full squirt when I activate the choke..

For the maximum pump stroke, move it to the top hole.  This should position the accelerator pump shaft approx. 7/16" above the top of the carbwith the throttle closed.

follow the instructions , doing each step in order,do not jump any steps.Make sure your float level is correct.Lots of times u have to do a little tweaking yo make things perfect.

Everything about the carb worked great other than the discharge noozle not squirting fuel. I think I have it now for I'm getting fuel quirting on initial start-up/choke activation.

Thanks all.......

See that the check valve under the nozzle, and the intake valve at the pump base are not leaking fuel backwards or sucking in air.  That could also cause your problem.

Sorry to tweak your thread a little , is the eddy avs a copy of the carter carb ? Does it look the same ?

Looks like they used the same casting/mold. Very simliar to the original. I wonder if it can be modified to accept the original choke configuration.. Would be nice to have a BRAND NEW AVS on Dana...
