Funny how things go. I glanced at this thread awhile back for one reason or another - but not because I had the same problem. I went for a ride on Saturday and my wife thought she smelled gas. I wasn't thinking much of it but when I got home, I took off the air cleaner and noticed some discoloration on my newly painted manifold. I started the car up and sure enough - drip - drip - drip. Turns out my inlet nut is stripped as well. I don't know what was holding it before - or maybe the leak was so small it was not noticeable. Anyway, took the carb into a local carb shop and he tried a repair nut but a pressure test revealed it did not seal. He said doing the heli-coil on the front inlet carb would almost certainly crack the housing. Yellowbird - you said you had success with the heli-coil with Cliff. Who is cliff and how do I contact him.
