New Weber 32/36 DGEV stalls on turns...

So I replaced my old card with a new Weber 32/36 DGEV and what a big diff in smoothing out my rough idle.. BUT The engine still stalls out when I idle around a turn. Runs fine if I am on the gas around a turn just at idle. I have a pressure regulator on it and have tried to set it from 2lb up to 4lb with no luck. Vacuum is good no leaks. Any ideas ???

John, I have read a ton on this float setting. Some say not to mess with it as it involves bending things and other say to do it. I read this well informed thread on here but it did not go into detail on how to fix the float setting. The crazy thing is the old carb (5+ years old) was a 32/36 and it did the same thing as well.. Where can I look to get detailed info on setting the floats.

FYI, I never had to mess with the float level on either of my Webers.

The fact that your engine displays the same symptoms with both the old and new carbs makes me think it's something else.

What are you plugs reading?

Matt,
The plugs were gaped at .45-.50. I just today bought Champion platinum plugs and the specks from Champion for the 258 call for .32.. So I put them at .32. still stalling out at idle clutch in around turns. runs great in gear around a tune!

Do you have power brakes? If so, are you on the brakes when it dies? Could be a hole in the brake booster.

I have found that the float height is the usual fix for this stalling on turns.

Try the height of 18mm from gasket to the top of the float.

The gasket is vertical, closing the needle valve, without the weight of the float on the dampening ball and spring, as shown in my picture.

Hope this helps.
