OK...update, my rebuild kit came in and I installed the new float adjusting screw and orings. No more leak and the the float level is perfect. New issue though that was not present before this. With 300k + miles on the engine it idles a little rough ( set about 1200 rpm )and missed a bit but that has been the norm for many years. When running down the road at 60 -65 mph all is great. But, when approaching a stop, putting the clutch to neutral, coasting, when I brake the rpm wants to drop off to about 500-600 rpm and the car stalls. Help??
