Thermoquad idle issue

the bottom of the plastic bowl has a slight raised Ridge to ensure positive seal by biting into the gasket. By filing the plastic body bottom you're probably introducing a leak. I've rebuilt a hundred TQ's and have never seen a warped bowl. I think that's an urban legend.
I agree there's nowhere near enough info to diagnose.
Hey Brother , I have a thermoquad 1971 6139s that has a leak in the primary circuit after
the engine is shut off
passenger side only drips badly at shut off . New build I did and new plastic floats and set to 1.00
float level . I suspect the o ring in the primary on the passenger side is not compressing enough to seal it , the plastic body has some weirdness at the o ring seat area on the passenger side .
When I got this car last week the TQ was flooding like nothing I have ever seen , .
now it is driveable and work well but at shut off if you look down at the cluster on the passenger side you can see liquid fuel and vapors . Take 10 seconds to re fire the 340 up .Want to get it to stop this ......thanks ...Joe
