Stall on 73 RR w/318 2-Barrel

[luther]

I have a 73 RR with 318 and Carter 2 barrel carb. I have a stall problem when turning right (so car is leaning left). Sometimes it stumbles and almost stalls. I have to put it in neutral and press the gas pedal to get around the corner to keep it from stalling. It is fine when turning left.
I took off the top & checked out the fuel level in the carb bowl after running the engine. It is within about 1/8" of the top, which looks OK. So the float appears to be letting enough fuel in. But don't know what it's doing when turning right--maybe the float is hanging up in that direction, but not the other?
Any ideas?
Thx, Luther

I thought that this was a post about torque converters.

What sort of corners are you talking about? Just a slow corner, like after a stop sign? Or something fast like an onramp? I had a problem once with stalling on corners and it turned out to be an ignition wire that was rubbing and shorting out when I turned, not a fuel problem at all.

Thanks for the suggestion. It happens worst on on-ramps (which are almost always turning right with a lot of leaning). But it can even happen when turning into my driveway. It's a real mystery!
Incidentally, I think ignition wires only short out on turns in Canada! Sorry for the feeble attempt at humor--just kidding!

My first thought was to make sure your battery is strapped down tight, it might be leaning over when you turn and grounding the positive cable / alternator out.

Does it happen on a full tank or when near empty only? But my guess would be something electrical.

i have to agree with others and think it is something electrical grounding.

Thanks for the ideas, gents. It happens on low or full tank. The battery is firmly tied down. I don't see any wires that might be causing the problem. However, I did see oil around the spark output on the coil (looked like the original coil). So I replaced the coil, but that didn't cure the problem.
If it is electrical I don't see how I would be able to keep it running by putting it in neutral and giving it more gas to prevent the stalling.
Still looking for the gremlin!

Well maybe fuel filter and/or pump. Perhaps your efforts to keep it running is getting your fuel level back to the appropriate level. try to replicate your problem in a big parking lot and let it die. Stop the car then check the fuel level in the carb. If low start with the filter then the pump.....about the only thing I can think of at this point.

If the carb chamber is full when this happens, and pumping it will keep it going, I cant see electrical, chamber i would think have fuel in it because pumping it keeps it going, Im thinking some type of vacuum leak when it turns this way, maybe PCV valve? a vacuum line getting pinched or pulling just a little loose.. I never heard of this one before and its the only thing i can think could do it, i know if i yank my hose from the PVC off when its running, it will try to quit, but hitting the gas it will keep it going, any chance something loose in it? How old is it? A couple things to try maybe...

WOOD U BELEEV???
Too much gas is not good! I discovered the carb float was letting too much fuel in, causing the engine to flood. (Don't know why it was only happening on right turns.) I duplicated the situation by running the passenger side front tire up on a wheel ramp. As soon as it got up the first time, it died. I popped off the carb top & it looked like maybe there was too much fuel in the bowl. After a couple trial and error adjustments, I pushed the float tab up to cut off fuel flow sooner and that cured it.
The carb is a rebuild from a parts store and the rebuilder obviously didn't adjust the float properly. This has been bugging me for months & bigger problems with the Runner (fried wires among others) had to be taken care of first.
But now it's fixed--Hooray!
Thanks for all the suggestions, guys!

Good deal man.. So much for a vacuum leak!

flooding,who would have guessed that.nice work finding that one.
