81 vette bogs on right turn

Hi folks,

I have an 81 with a computer delete, and a 1406 Edelbrock carb installed.

On 90* right turns, ONLY, the car bogs RPM almost to the point of stalling out. If fact it DID stall completely yesterday.

Other than that, the car runs sweetly.

What should I look for?

Thanks!

Raise your float level in your carb.

If the float level is the issue, why would it bog on RIGHT turns, and not on LEFT turns?

Don't know what carb you have but it might be on hinged left or right, and it is more sensitive on one side more then the other if set too low. When mine is set too low it dies on hard braking.

Any thoughts about fuel pressure being too high?

Might it need a regulator installed to dial down hepressure?

Any other ideas?

You have 2 floats hinged from the back, one on the left side and one on the right side, I would check the float level and the needle and seat for an obstruction.

Thank you.

Any guess as to which side is more likely the culprit?

I'll take a guess and say it's the right side. But, does it really matter? They both need to be set properly, so just set 'em.

Thanks, Scott.

I appreciate that and will investigate.

Point is, that it only does it on RIGHT turns, and I'd be more understanding if the floats were left/right orientation instead of fore/aft, if you understand my thoughts.

It doesn't really have as much to do with how the floats work, as it does with having the fuel level in the bowl set to the right height. I don't know enough about them to tell you if it's the right or left float that needs the adjustment. Tell ya what, pop the top off the carb, and adjust whichever float is low to match the other one, and see how that works. Now that I think about it, it might be the left one, as a right turn will make the fuel want to slosh up against the outside wall of the fuel bowl, uncovering the part where the fuel enters the carb if the level is to low.

soaked floats

seems to me I remember floats becoming saturated with gas and becoming heavy. This could let it be sensitive to turning as the weight would make it move.
