Stalling during right hand turns
This is weird. I have a SBC 307 w/ an Edelbrock #1451 650 cfm quad carb and a Th 350 trans set up in my 37 Ply. The engine and trans are circa 1970 w/ stock single point ignition. It has std. GM power steering. The trans is consistently downshifting properly. The car wants to stall ocasionally when I make a slow (15 mph +/-) right hand turn. It does not do it consistently. I have set the carb according to Edelbrock specs and have rechecked it on another occasion to be sure it was right. I have good vacuum. I cannot figure out what the problem is. My only suspicion is the floats may be too high. Any suggestions?

My Buddies Camero did that. Was a problem with the steering pump, Well.. Not a problem per say, but drew too much hp to run on idle. Try turning while parked. That was his prob anyway.

Sounds like floats to high to me.

Or you could sell it to a dirt burner who only turns left.

I remember reading about this very problem about 30 years ago in Popular Mechanix. The culprit was a small hole in the fuel line from the fuel tank. The fuel line was rubbing up against the frame and eventually rubber a small hole on the back side. When driving straight down the road there was no problem because the hole was sealed up, but when the driver turned to the right, the body flexed away from the frame just enough for the hole to open up and the fuel pump would then suck air instead of fuel. Engine would die, but then restart immediately after.

Another thing you can do is to check your wiring. If a wire has had the insulation burnt off, It could be swinging into something and shorting out when you turn right?

Easiest thing would be to make left turns only... <img src="graemlins/mwink.gif" border="0" alt="[mwink]" />

Since I don't know when the stalling will occur, I have decided to make right hand turns only when there is no other option. I wear tri-focals and cannot see anything up close, so loking for apinhole is impossible. I like the idea of using the car for left hand dirt tracks. The wiring has been checked and found to be OK. The steering pump idea was tried and the car kept running with only a slight decrease in rpm from the added load. I will set the floats an additional 1/16" lower and see if that makes the fix.
Thanks for all the creative "out-of-the-box" ideas. That's what makes us all Car Nuts!

I have a stock 455 in My 81 Cuttlass. It runs a standard Q-jet. Anyway, as I would break to a stop, the engine would surge horribly and when I made a right or left hand turn the engine would stumble badly. Finally after many tear downs of the carb, I discovered an extra washer under the needle and seat. Consequently, I was unable to obtain the correct float level...it was always running rich. I took out one of the washers and you guessed it, the motor is running fine!

hey jpd, I had the same problem with my 69 camaro, except it happened on any hard turn. Now, I don't know ANYTHING about carbs, or how to tune them, but I replaced the accelerator pump and I never had the problem again. I didn't even change it for that reason. In order to keep it from stalling, I just pushed in the clutch and gave it some gas through the turn...it was the easiest fix I could think of

From <a href="http://www.edelbrock.com" target="_blank">www.edelbrock.com</a> : Incorrect float settings can cause drip-flooding, hard turn stalling and flooding upon acceleration. To cure the problem, simply readjust the float level to 7/16" using a scale or a 7/16" drill bit as shown in the photo at right. Instructions on how to check the float level can be found in the carburetor owner's manual.
If you go to edelbrock.com,look at the left and scroll down to and click TECHNICAL INFORMATION and click INSTALLATION TIPS and scroll down to EDELBROCK PERFORMER SERIES CARBS, It explains what to do under number 1.....Jay

s15laynrubba, PROBLEM FIXED! I did exactly what the Edelbrock manual recommended. However, I have found that increasing the float adjustment from 7/16" to 1/2" has resolved the problem. I do have a small leak out the top opening of the accellerator pump, so I might consider replacing it to see if that problem goes away. Thanks for the advice.

I dunno if ya got somekind of a steering colume with the key in it in your car but I had that prob in one of my winter rats.It was the steering colume.Everytime I would make a right turn it would kill power to the coil.

I had the exact same problem. The car would stall when turning right. I found this post on the internet, adjusted my floats, and now the car runs fine. I also have an Edelbrock Preformer Carb. I would say that this solution would apply to the call stalling while turning right or left.
