Be careful using an 'O' ring in the carb. There have been reports of them getting sucked into the engine and can cause you real grief. If you get a good seal with the silicone you will not need that 'O' ring. Good luck.
Thank you very much for your advice. Will clean all parts again and try gasket sealer on intake/carb connection. Puzzles me why the designed fastner connection won't take care of the air leak - lead me to the possibility of a defective part.
