Addlightness93 Posted September 1 Share Posted September 1 Hello! Looking for some guidance. Have a Super sprint with a 1700 cross flow and twin DCOE 40’s. When I turn sharply to the right I get a whiff of raw fuel, very strong. Doesn’t happen when turning to the left. It also happens if I jack the car up quite high on the right side. I replaced the carb gaskets (rubber) hoping it would help, and adjusted the float levels (as best I could, first time). Wondering if one of the floats is getting stuck because of the G forces. For reference I have plastic floats. Thank you for any and all insights! 1 Link to comment Share on other sites More sharing options...
MV8 Posted September 1 Share Posted September 1 Float level checked? Link to comment Share on other sites More sharing options...

MV8 Posted September 1 Share Posted September 1 As long as they float, either is fine. Link to comment Share on other sites More sharing options...
SENC Posted September 2 Share Posted September 2 (edited) Which DCOE40 type? I just read yesterday a comment elsewhere that the posts from which the floats hang were different length in early DCOE40s (that used brass) than later. Conceptually it shouldn't matter as you can adjust the flange on the floats to achieve the level you want. I wouldn't change them unless you have a known reason to do so (brass can develop holes and hold gas, pin is bent or worn and float can't move freely or alternately be too loose and jiggly, etc). Check your fuel level in both carbs from the top after letting it idle. Remove a main jet and tube in each and look down from above with a light. Part way down you should see the orifice through which gas is pulled into the venturi - it's a good reference point for comparing fuel levels across carbs. Alternately use a paper matchstick or similar to actually measure and compare. If they are different that might suggest one of them has a float issue to investigate.
