STALL OUT PROBLEM!!

4SPEED427 · A Poncho Legend!

It seems to me there is something in the carb that causes that but I forget what it is. Float level maybe. Anyone?

Lefty · Uber Guru

float could have a leak in it which would make it sink instead of float.
you may have to take it apart and test the float in water.

SET TO LOW !!

Is there a dash pot on the throttle on a one barrel carb like the two barrel and four barrel carbs. This was ussed as a anti stall device when hard braking. If so maybe not working or needs adjusting.

important part is to be 1 3/4 from bottom of carb to bottom of float

thanks for the input fellow c/per`s that makes since with the float set to low..i`ll be pulling that little one barrel apart tonight and checking the level..so after pulling the top part of the carb off would you say it should have about 1/2 or 3/4 full of gas in the bowl..

Do these one barrels have an idle mixture set screw? If it was a 2 or 4 barrel I'd be settng that up first, then adjust idle speed before taking the carb apart.

yes ray it does have a single mixture screw..

If in motion, does it make any difference if you're moving forward or backwards?.
There was a thread on the Yenko site w/ a similar problem about a year ago that turned out to be the battery!.
I'll try and dig the thread up as it covered lots of good things to check before the problem was found..

it runs fine in park..and it doesn`t stall when i`am in reverse and hit the brakes..if i go very easy on the brake pedal it`s fine.but hard on the brakes or left hand turn it conks out like it starving for gas..

HI i remeber that one about the battery the guy tried every thing battery would short out inside worth a try

I HAD THIS PROBLEM YEARS AGO IN MY '69 NOVA. CAR WOULD DIE MAKING LEFT-HAND TURNS, TURNED OUT IT WAS THE BATTERY MOVING AND SHORTING OUT ON THE FENDER. SECURED THE BATTERY, PROBLEM GONE. NOT SURE IF THIS IS YOUR PROBLEM, BUT MAYBE WORTH CHECKING OUT.

wagon64sd · Guru

it wouldn`t be the battery,,i share it with my 69 and it works fine in it. wink

IS THE BATTERY TIED/BOLTED DOWN OR LOOSE IN THE ACADIAN?

thanks for that thought..i don`t have the battery secured down..

wagon64sd · Guru

just thinking about the battery,,should their be a ground wire coming from the negative side of the bettery to the body??

Ghost Post · Poncho Master!

Does touching the brakes while stationary makes any difference?.
While in motion or not, does it always run Ok at higher revs?.

there should be a neg wire from batt to rad support and a small copper braid from firewall to under valve cover. and to be 100% sure i took a neg wire from under same bolt on rad support to engine block
I burnt out a wiring harness when the braid from firewall to valve cover broke and i could not figure out why a ground wire in my harness was getting red hot and cooking the harness..
it was using the harness to get the neg for starter

carb bowl filling up, check float.

59poncho · Poncho Master!

i had the same sort of problems with the 2-barrel and it was the float as well.

wagon64sd · Guru

i pulled the top half off the carb..lots of gas in the bowl..i don`t think it`s gas related. as soon as i put the car in gear (drive or reverse) it stalls..could it be a transmission problem.. confuse i did a bit of research and a bad" lock up solenoid" will cause this problem.anybody heard of this before.....

4SPEED427 · A Poncho Legend!

Do you have a later model transmsission in there? The original trans would not have a lock up converter, so no solenoid for the converter in it that could be causing it.

wagon64sd · Guru

it`s the original powerglide..no tranny lines to the rad..carl your saying the tranny has nothing to do with the problem..

Beaumont4008 · Uber Guru

Did you try re adjusting the air idle mixture screws yet with a vacuum gauge ? They have to be set when engine warmed up not cold or will stall out when put into gear.
