i noticed the same problem here several times tech. on my 42 mikuni after sitting dry for 2 years did the same thing. that rubber point needs to soak in some gas for 48 hrs , small bowl or glass jar , then it swells and softens to make a seat . next problem is nowdays with ethonal gas older rubber carb parts don't get along. notice on a brand new truck it says 85 complyant. 85 % gas 15% ethonal.
