My 68 911. Setting the float levels. All good until I get to drivers side rear. Using the external PMO gauge it almost empties. Then over flows. I have changed the float and the float valve. Still the same issue. What am I missing ??? I can get it to settle. A bit of a rev etc and I can make it misbehave at an idle and my engine runs ruff.
Side note my idle mixtures on all six seem to Bugger all 😦
